arm64: Add system register encoding for PSTATE.PAN

Browse source

Although we already have the primitives to set PSTATE.PAN with an
immediate, we don't have a way to read the current state nor set
it ot an arbitrary value (i.e. we can generally save/restore it).

Thankfully, all that is missing for this is the definition for
the PAN pseudo system register, here named SYS_PSTATE_PAN.
