lib: Add support for M4F on AM64x SoCs

The TI K3 AM64x SoCs have a M4F core in MCU domian. The M4F is typically
used with safety applications. Non safety applications may use M4F as a
remote processor with virtio based rpmsg communications to the Host
linux applications.

Add support for M4F for AM64x SoCs in ti_rpmsg_char library. The library
version is bumped to 0.3.1 to account for the modfications done to
support M4F remote processor.
