arm64: Rename reserved values for CTR_EL0.L1Ip
We now have *two* values for CTR_EL0.L1Ip that are reserved.
Which makes things a bit awkward. In order to lift the ambiguity,
rename RESERVED (0b01) to RESERVED_AIVIVT, and VPIPT (0b00) to
RESERVED_VPIPT.
This makes it clear which of these meant what, and I'm sure
archeologists will find it useful...
