remoteproc: k3: Refactor .stop rproc ops into common driver

Browse Source 
The .stop rproc ops implementations in TI K3 DSP and M4 remoteproc
drivers put the remote processor into reset. Refactor the
implementations into ti_k3_common.c driver as k3_rproc_stop() and
register this common function as .stop ops in DSP and M4 drivers.
