[PATCH v3 0/4] Introduce K3 remoteproc driver for M4 subsystem

[Judith Mendez]

Some K3 devices like am62x and am64x have a M4 processor in the MCU
voltage domain. This patch series introduces remoteproc M4 driver which
will be used to load firmware into and start the M4 remote core.

This series also adds support for R5F cores on am64x SoCs in patch 2/4,
sets up environment to load FW in remote cores in patch 3/4, and enables
config options for R5F and M4 remoteproc support in patch 4/4.

This patch series was tested on am64x EVM using commands:

=> setenv dorprocboot 1
=> run boot_rprocs

Changes since v2:
- Cleanup unused labels
- Remove optional init and reset functions which do not do anything
- In stop, call unprepare() instead of ti_sci_proc_power_domain_off()
  Since it is already a wrapper for ti_sci_proc_power_domain_off
