ARM: MX3: make CPU revision number detection work on all boards

Commit 52939c03 (ARM: MX3: fix CPU revision number detection) started
using the CPU's SREV register for revision number detection. This
makes it mandatory to have a valid SPBA0 mapping. Add this to the
global map_io code instead of adding multiple copies for each board.
