This adds code to handle two new guest-accessible special-purpose registers on POWER9: TIDR (thread ID register) and PSSCR (processor stop status and control register). They are context-switched between host and guest, and the guest values can be read and set via the one_reg interface. The PSSCR contains some fields which are guest-accessible and some which are only accessible in hypervisor mode. We only allow the guest-accessible fields to be read or set by userspace.
