psc: Add support for mutex mailbox
...
This change adds support for mailbox with mutex.
In OESP/SB, GP mailboxes are used. Since they are mailbox with mutex,
the driver needs to acquire mutex before using it.

drivers: Fix missing headers for Linux v6.8
...
For Linux v6.8, commit ef175b29a242 ("of: Stop circularly including
of_device.h and of_platform.h") updated the OF headers included by these
header files. This breaks the build for various drivers and so fix this
by including the headers that are actually needed for each driver.
