This patch readjusts the SPR's adds support for IAMR/AMR
UAMOR/AMOR based on their supported ISA revisions.
There is also support for printing the PIDR/TIDR for
ISA 300 and PSSCR and PTCR in ISA 300 hypervisor mode.
SPRN_PSSCR_PR is the privileged mode access and is used
when we are not in hypervisor mode.
