MHU (Message Handling Unit) enables software to raise interrupts to
the processor cores. It is enabled in SSE 200 subsystems.
This patch aims to implement inter processor communication.

Add a minimal sample that showcases minimal ROM sizes. It can be built
in several configurations, all very restrictive when it comes to
features enabled in order to verify the fact that we can fit in small
devices and to be able to accurately measure the sizes of the kernel's
basic features.

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.
