drm/i915/gt: Correct prefix on a few registers

We have a few registers that have existed for several hardware
generations, but are only used by the driver on Xe_HP and beyond.  In
cases where the Xe_HP version of the register is now replicated and uses
multicast behavior, but earlier generations were singleton, let's change
the register prefix to "XEHP_" to help clarify that we're using the
newer multicast form of the register.
