The `cpu-power-states` property needs to be defined at SoC dts files,
since it's a property of the SoC, not board.

pm_device_runtime_get() uses a semaphore to protect resources.
pm_device_runtime_get() blocked forever until obtaining the lock, making
it unusable from contexts where blocking is not allowed, e.g. ISRs. With
this patch, we give the chance to use the function from an ISR by not
waiting on the lock and returning -EWOULDBLOCK instead. If device is
suspending (from a previous put_async() operation) the same value is
returned as we can't wait either.

Adds driver for pwm on xmc4xxx using Capture Compare Unit 8 (CCU8)
module. There are two CCU8 nodes with each one having four slices.
Each slice has two output channels.
Unlike CCU4, this module can generate complementary high-side/low-side
signals for each output channel. A variable dead time can be added
during the off to on transitions to make sure that the
high-side/low-side signals are not on at the same time.

Adds driver for pwm on xmc4xxx using Capture Compare Unit 4 (CCU4)
module. There are four CCU4 with each one having four channels
Thus it's possible to have up to 16 pwm output signals. The output of
each channel can only be connected to a specific port/pin. The possible
connection and gpio configurations are defined using pinctrl.
The CCU4 module also has a capture mode. Capture support will be added
in the future.

Pinmuxing is now done by a pinctrl driver, not by board.c,
so the code used previously for pinmuxing can be removed.
Fixes#59186.

The malloc arena/heap size setting can be adjusted using different
Kconfig options, depending on the libc implementation. This means
prj.conf can't be used to set this value on projects that can be built
for multiple libcs without generating a Kconfig warning.

Effectively, this option changes code triple in device descriptor.
Although the name is misleading, renaming it would again lead
to negative user experiences. Instead, clarify what the option does
and always select it where it is required.

Add mailbox and interrupt-controller nodes used for
inter-process communication.
Add also the dt binding for the interrupt-controller.
For now, this is used just to fix some compile errors,
since the mailbox requires an interrupt-controller.
For DSP, we have a direct interrupt line to the core.

Introduces support for SoC-specific input-edge-detect configuration to
the CC13/26xx pinctrl driver.
Signed-off-by: Florian Grandel <fgrandel@code-for-humans.de>
CC13/26xx's pinctrl_cc13xx_cc26xx.c driver included ioc.h and
(indirectly) pinctrl_soc.h which contained duplicate defines.
This change removes the header conflict and redundant definitions.
This prepares for subsequent changes in this change set that add
additional flags to the pinctrl driver which would otherwise trigger the
header conflict.

Adds a helper function for initializing devices into the expected power
state, through the devices `pm_device_action_cb_t`. This eliminates code
duplication between the init functions and the PM callback.
The expected device states in order of priority are:
* No power applied to device, `OFF`
* `zephyr,pm-device-runtime-auto` enabled, `SUSPEND`
* Otherwise, `ACTIVE`

CONTAINER_OF() cannot be used to obtain the device pointer from its
data pointer as this data is not contained in the device structure.
Instead, use a dedicated member in the device data structure to store
the device pointer.
