The release_tsp() implementations in the TI K3 R5, DSP and M4 remoteproc
drivers 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 use this common function throughout in R5, DSP and M4 drivers.

The reserved_mem_init() implementations in the R5, DSP and M4 remoteproc

Refactor these functions into the ti_k3_common.c driver as
k3_reserved_mem_init() and use this common function throughout in R5,

The of_get_memories() implementations in the TI K3 R5, DSP and M4
remoteproc drivers initialize and assign memory regions used by the
remote processor in the same way. Refactor these implementations into
ti_k3_common.c driver as k3_rproc_of_get_memories() use this common
function for mem initialization in R5, DSP and M4 drivers.
Note: The TCM addresses for R5 core are configurable based on the
'loczrama' setting. Therefore, override the bus_addr assignment done by
the common function for TCMs of R5 remote processors by reading the
'loczrama' DT property in k3_r5_core_of_get_internal_memories().

The .da_to_va rproc ops implementations in TI K3 R5, DSP and M4
remoteproc drivers return the Kernel virtual address for a
corresponding rproc device address.
Refactor the implementations into the ti_k3_common.c driver as
k3_rproc_da_to_va and use this common function for address translation
of DDR and internal memory regions in R5, DSP and M4 drivers.
Note: The R5 SRAM memory translations are still handled in the .da_to_va
ops of the R5 remoteproc driver.

The k3_dsp_rproc_start() function sets the boot vector and releases the
reset on the remote processor. Whereas, the k3_m4_rproc_start() function
only needs to release the reset.
Refactor the k3_m4_rproc_start() into ti_k3_common.c as k3_rproc_start()
and align the DSP and M4 drivers to invoke this common function when
releasing the reset on the remote processor.
