[ARCH_REG 2] Enable architected register data reserve in the host

Keep a reserve space for each proc where sbe can dump all the
architected register state data, which host will use to build the
hdat in mpipl path. Host will pass on this address to each SBE in
the stash after calculating the respective offset basis the proc.
