The SOF mailbox.h provides an interface to host-DSP mailboxes, which is used widely in SOF IPC and debug code. This interface is OS agnostistic and only relies on platform/lib/mailbox.h to define the mailbox locations, and rtos/cache.h to define portable cache primitives to invalidate/writeback mailbox data before/after use. The amount of RTOS variation does not seem to warrant branching the whole mailbox.h to RTOS layer. Move mailbox.h back to application interface, so the single implementation can be shared.
