The existing local APIC timer driver (loapic_timer.c) has bitrotted
and doesn't support TICKLESS_KERNEL, which is the preferred mode of
operation. This patch introduces a completely new driver, called
the APIC timer driver - the name is changed to allow the drivers to
continue to coexist in the short term, and also because "APIC timer"
isn't ambiguous (the I/O APICs do not have timers).
This driver makes no attempt to work with the MVIC timer as the
previous version did, because MVIC support is deprecated.

This is a graphical configuration interface written in Tkinter. Like
menuconfig.py, it supports showing all symbols (with invisible symbols
in red) and jumping directly to symbols. Symbol values can also be
changed directly from the jump-to dialog.
This interface should feel a lot smoother than menuconfig.py on Windows.
When single-menu mode is enabled, a single menu is shown at a time, like
in the terminal menuconfig. Only this mode distinguishes between symbols
defined with 'config' and symbols defined with 'menuconfig'.
Compatible with both Python 2 and Python 3. Has been tested on X11,
Windows, and macOS.

This commit adds driver support for ADC1 on all 8 supported series of
stm32 with resolution and conversion time selection and calibration.
Currently DMA is not supported for all series, and without it, zephyr
won't be able to catch up ADC's end of conversion interrupt, so this
version of the driver supports one channel conversion only. Users want
multi-channel conversion should use multiple sequences in their app
code.
This driver uses LL lib rather than HAL because the current HAL lib for
ADC will call HAL_DMA_* functions rather than using zephyr's common DMA
interface, so that way the driver will break the consistency of the
code.
This driver has been tested on multiple nucleo boards including
NUCLEO_F091RC/F103RB/F207ZG/F302R8/F401RE/F746ZG/L073RZ/L476RG and all
passed the test cases in tests/drivers/adc/adc_api. If the external ADC
line is floating, it may fail the tests since ADC may get 0V and the
test cases think 0 is failing. Connect it to any voltage source between
0-3.3V will help passing the test cases.

The MCP2515 is a CAN controller that can be connected via SPI to an
host MCU. This driver adds support for the MCP2515 as a new driver in
the CAN subsystem.
As it is a SPI peripheral it uses a thread for its interrupt
handling and the received message filtering is done inside this
interrupt thread, as the MCP2515 filter capabilities are not sufficient
for the Zephyr CAN interface.
The driver was validated with an external CAN logger and the adjusted
CAN sample application.

A parallel PCI implementation ("pcie") is added with features for PCIe.
In particular, message-signaled interrupts (MSI) are supported, which
are essential to the use of any non-trivial PCIe device.
The NS16550 UART driver is modified to use pcie.
pcie is a complete replacement for the old PCI support ("pci"). It is
smaller, by an order of magnitude, and cleaner. Both pci and pcie can
(and do) coexist in the same builds, but the intent is to rework any
existing drivers that depend on pci and ultimately remove pci entirely.
This patch is large, but things in mirror are smaller than they appear.
Most of the modified files are configuration-related, and are changed
only slightly to accommodate the modified UART driver.
Deficiencies:
64-bit support is minimal. The code works fine with 64-bit capable
devices, but will not cooperate with MMIO regions (or MSI targets) that
have high bits set. This is not needed on any current boards, and is
unlikely to be needed in the future. Only superficial changes would
be required if we change our minds.
The method specifying PCI endpoints in devicetree is somewhat kludgey.
The "right" way would be to hang PCI devices off a topological tree;
while this would be more aesthetically pleasing, I don't think it's
worth the effort, given our non-standard use of devicetree.

When the console UART is a PCI device, and PCI debug logging is enabled,
the system crashes because the UART is initialized before logging, but
the UART initialization invokes the PCI subsystem which invokes logging.
Reordering the initialization sequence will not fix this chicken/egg.
Luckily, the LOG_DBG() calls in the PCI subsystem appear to be bitrot
leftovers from early development, so they are simply removed.
Also mark myself as the owner of the PCI subsystem.

If CONFIG_MPU_REQUIRES_POWER_OF_TWO_ALIGNMENT is enabled,
the app shared memory partition may cause waste of memory
due to the need for padding.
For example, tests/subsys/jwt and board mps2_an385:
z_test_mem_partition: addr 0x20000000, size 52
z_libc_partition : addr 0x20000040, size 4
k_mbedtls_partition : addr 0x20008000, size 32736
ending at 0x2000ffff, taking up 65536 bytes
With power-of-two size and alignment requirement,
k_mbedtls_partition takes up 32KB memory and needs to be
aligned on 32KB boundary. If the above partitions are
ordered as shown, there needs to be a lot of padding
after z_libc_partition before k_mbedtls_partition can
start. In order to minimize padding, these partitions
need to be sort by size in descending order.
After the changes here, the partitions are:
k_mbedtls_partition : addr 0x20000000, size 32736
z_test_mem_partition: addr 0x20008000, size 52
z_libc_partition : addr 0x20008040, size 4
ending at 0x2000805f, taking up 32864 bytes
With the above example, sorting results in a saving
of 32672 bytes of saving.
