arm64: Add override for WFxT
Add an override for WFxT support within ID_AA64ISAR2_EL1 to allow
it to be disabled using the new arm64.nowfxt command line parameter.
This accompanies the idle=nop param introduced in a previous patch
series [1] in dealing with misbehaving WFI and WFIT instructions on
Apple Silicon SoCs, and eases debugging of other quirky WFxT
implementations.
