We generally use symbolic field names generated via NV_FTR() when we filter the feature registers for nested virtualisation but when the current format was adopted there was no symbolic definition for ID_AA64PFR0_EL1.RME so it was instead specified using a raw GENMASK_ULL(). Since the field has now been specified in sysreg we can replace this with the symbolic name in order to make things marginally more legible.
