[PATCH v8 20/20] remoteproc: k3: Refactor release_tsp() functions into common driver

[Beleswar Padhi]

The k3_{dsp_/m4_}release_tsp() functions release the TI-SCI processor
control of a remote processor, which is auto triggered upon device
removal. Refactor these functions into ti_k3_common.c driver as
k3_release_tsp() and align DSP and M4 drivers to use this common
function throughout.
