Introduce a wkup_m3_ipc driver to handle communication between the MPU and Cortex M3 wkup_m3 present on am335x. This driver is responsible for actually booting the wkup_m3_rproc and also handling all IPC which is done using the IPC registers in the control module, a mailbox, and a separate interrupt back from the wkup_m3. A small API is exposed for executing specific power commands, which include configuring for low power mode, request a transition to a low power mode, and status info on a previous transition.

Say y here to support the Keystone multicore Navigator Queue

Manager support. The Queue Manager is a hardware module that

Packets are queued/de-queued by writing/reading descriptor address

TI AM33XX and AM43XX have a Cortex M3, the Wakeup M3, to handle

low power transitions. This IPC driver provides the necessary API

to communicate and use the Wakeup M3 for PM features like suspend

resume and boots it using wkup_m3_rproc driver.
