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

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.
