target-arm: Add registers for PMSAv7

Browse source 
Define the arm CP registers for PMSAv7 and their accessor functions.
RGNR serves as a shared index that indexes into arrays storing the
DRBAR, DRSR and DRACR registers. DRBAR and friends have to be VMSDd
separately from the CP interface using a new PMSA specific VMSD
subsection.
