soc: ti: pruss: Rename pruss_regmap_read()/update() API

The pruss_regmap_read() and pruss_regmap_update() API were designed
to support reading and updating any of the registers within the
CFG, MII-RT or IEP sub-modules. The management of MII-RT and IEP
submodules is dropped from the PRUSS platform driver, so simplify
the functionality of these functions to just deal with the CFG
sub-module. Both the functions have been renamed appropriately to
pruss_cfg_read() and pruss_cfg_update(), and all existing callsites
updated accordingly.
