Add a CPU frequency scaling subsystem, allowing a policy
algorithm to control the frequency of a given SoC/MCU
automatically at runtime.
Implement a basic, "on-demand" policy algorithm which
iterates through the P-states supported by the SoC and
selects the first P-state where it's trigger threshold is
less than the CPU load.
The CPU frequency scaling subsystem does not currently
support SMP. The CPU load measurement can be made to support
SMP since statistics are measured from the scheduler.

Implement CPU load measurement subsystem. The statistics
used to calcualte the load are taken from the scheduler.
Specifically, the number of cycles used by the idle thread.

GIC ITS depends on kernel heap, so move GIC initialize to be behind of
heap which initialization priority is CONFIG_KERNEL_INIT_PRIORITY_OBJECTS
which is 30 by default.
MU mailbox and SCMI objects depend on GIC, so set their init priority
to be same with GIC, the initialization sequence decided by the dts
dependency although they use the same init priority.

The call to k_sleep() is not safe as dai_dmic_probe() is called
from PM dmic_pm_action() and k_can_yield() may be false.
Problem was caught on Intel WCL ADSP platform with SOF as application
and a Zephyr build with asserts enabled.
Fix the issue by using k_busy_wait() instead.

Add build tests for the following missing devices:

These tests verify the expected returned value and device state for

documentation.

This fix makes sure that do_device_init() returns a negative value if
the device's initialization failed. Previously, it mistakely returned
+errno instead of -errno.
This oversight happened during the refactoring of z_sys_init_run_level()
to support deferred initialization, from which most of do_device_init()
code derives. The rc value computed and stored in dev->state->init_res
is the POSITIVE value of the resulting errno. Returning rc therefore
breaks the convention of a negative value to signal failure.
