remoteproc: k3: Refactor mem_release() functions into common driver

The mem_release() implementations in the TI K3 R5, DSP and M4 remoteproc
drivers release the reserved memory of the device, which get auto
triggered upon device removal.

Refactor these functions into ti_k3_common.c driver as k3_mem_release()
and use this common function in R5, DSP and M4 drivers.
