Add framework for device Idle Power Management(IPM)
for suspending devices based on device idle. This will
help in saving power even while system(CPU) is active.
The framework uses device_set_power_state() API set the
device power state accordingly based on the usage count.

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.

Running checkpatch in pre-commit hook could be a constraint
for day to day work. Though, running it before pushing to

The mbedtls library has some globals which results in faults
when user mode tries to access them.
Instantiate a memory partition for mbedtls's globals.
The linker will place all globals found by building this
library into this partition.

drivers/wifi/ is closely related to the (IP) network stack, so
shouldn't be left without owners, so use the same as for Ethernet.
Also, extend, don't replace reviewers for drivers/wifi/eswifi based

Also, add a reminder about this processing order at the top of file.

According to https://help.github.com/articles/about-codeowners/:
The `docs/*` pattern will match files like
`docs/getting-started.md` but not further nested files like
`docs/build-app/troubleshooting.md`.
