ppc: Add macros to register hypervisor mode SPRs
The current set of spr_register_* macros only take the user and
supervisor function pointers. To make the transition easy, we
don't change that but we add "_hv" variants that can be used to
register all 3 sets.
To simplify the transition, users of the "old" macro will set the
hypervisor callback to be the same as the supervisor one. The new
registration function only needs to be used for registers that are
either hypervisor only or behave differently in HV mode.
