soc: ti: pruss: factor out memories setup

Factor out memories setup code from probe() into a new function
pruss_of_setup_memories().  This sets the stage for introducing auto
cleanup of the device node (done in the subsequent patch), since the
clean up depends on the scope of the pointer and factoring out
code into a separate function obviously limits the scope of the various
variables used in that function.

Apart from the above, this change also has the advantage of making the
code look more neat.

While at it, use dev_err_probe() instead of plain dev_err() as this new
function is called by the probe().
