This commit introduce 'USE_SWITCH' feature into cortex-A/R(aarch32)
architecture
For introducing USE_SWITCH, the exception entry and exit are unified via
`z_arm_cortex_ar_enter_exc` and `z_arm_cortex_ar_exit_exc`. All
exceptions including ISR are using this way to enter and exit exception
handler.
Differentiate exception depth and interrupt depth. Allow doing
context switch when exception depth greater than 1 but not allow doing
this when interrupt depth greater than 1.
Currently, USE_SWITCH doesn't support FPU_SHARING and USERSPACE.

Store the current CPU's struct _cpu instance into TPIDRURO, so that the
CPU core can get its struct _cpu instance by reading TPIDRURO. This is
useful in the SMP system.

Replace the TLS base address pointer from TPIDRURO to TPIDRURW.
The difference between them is that TPIDRURO is read-only in user mode
but TPIDRURW isn't. So TPIDRURO is much more suitable for store
the address of _kernel.CPU[n]. For this reason, this commit replaces
the base pointer of the TLS area.

Since the accelerometer's HM (high-performance mode) bit is forced to 1,
the 1.6Hz frequency is available by setting the ODR to 11.
1.6Hz is a low-power mode that conserves energy and is suitable for
some applications, such as determining the orientation (portrait or
landscape) of a device.

Add an initial test based on the broadcast audio source/sink samples
which runs them together and after waiting for a predefined
amount of time, checks how many audio packets has the
sink received, and if over a threshold, passes the test.
This test can be expanded after to cover more functionality from
these samples.

Use ACPI_MADT_LOCAL_APIC instead of struct acpi_madt_local_apic. In the
same go, switch to IF_ENABLED from ifdef - slightly more readable, and
this keeps some static analyzers happy (e.g. upstream Compliance check).

The ACPI table signature is not null terminated, so a precision needs to
be provided in format strings. There was an attempt to do this, but it
was done in an incorrect way, which resulted in garbage characters
getting printed.

For most types, ACPICA provides both a struct name as well as a typedef.
The struct names follow the exact same naming style as Zephyr's ACPI
API, which makes it impossible to distinguish which type is defined by
Zephyr and which comes from ACPICA. It's therefore better to use the
typedefs, since they follow a distinct style compared to the Zephyr API.

The ACPI shell command create way too much vertical empty space. Remove
the unnecesary newlines and use indentation to indicate grouping of
lines. At the same time, place case statments with variable declarations
behind {} since otherwise both the Zephyr compliance checker and some
other static analyzers get confused by the code in the branch.

The acpi_get_irq_table() function takes a pointer to a table that can
come from anywhere, i.e. it doesn't have to be the acpi.pci_prt.table
that acpi.c uses. Because of this, the correct place to iterate and
process the acpi.pci_prt_table is in the function that actually passes
acpi.pci_prt_table to the acpi_get_irq_table() function.
Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
The acpi_get_irq_routing_table() takes a pointer to an array of
ACPI_PCI_ROUTING_TABLE elements rather than a generic buffer pointer
(e.g. void *).
Because of the above, it makes sense to specify the array size as an
actual ARRAY_SIZE() value, since it makes no sense to accept buffers
which are not a multiple of sizeof(ACPI_PCI_ROUTING_TABLE) long.

If the CONFIG_PCIE_PRT option is disabled it makes no sense to bloat the
ACPI build with PRT-related code or static tables. The diff looks a bit
larger since functions in acpi.c had to be shuffled around to be able to
be included in a single "#ifdef CONFIG_PCIE_PRT" block.

The acpi_tables array is only needed for systems where dynamic memory
allocation is not available during the early ACPI init phase. In the
Zephyr case we can immediately start using k_malloc, so this is
unnecessary.

If the server has synchronized to the PA and detected that the BIS is
encrypted, the server writes a value of 0x01 (Broadcast_Code
required) to the BIG_Encryption field of the Broadcast Receive State
characteristic to request a client to provide a Broadcast_Code.
In PTS BASS/SR/CP/BV-14-C test case the PTS (client) expects that the
new value of the Broadcast Receive State characteristicstate will be
notified, so the PTS could sent Set Broadcast_Code operation to the

Commit c6e3bac4f changed the core clock frequency of LPC55XXX series.
That clock is used by the cortex-m systick timer, which is the
default timer used for system time in zephyr on this series.
The bug is that the config SYS_CLOCK_HW_CYCLES_PER_SEC default was not
updated on the affected platforms to account for this change, so system
time is currently recorded as 150% of reality. Fix this by changing the
kconfig to be set automatically at SOC level and remove board defaults.

The way that the QSPI peripheral is activated has been changed in
nrfx 3.2.0. Now the peripheral is not activated during the driver
initialization. Instead, the driver activates the peripheral when
the first operation is requested or when `nrfx_qspi_activate()` is
called. In case of XIP, the latter needs to be used, as there may
be no standard operation request.
