arm64: Repaint ID_AA64MMFR2_EL1.IDS description
ID_AA64MMFR2_EL1.IDS, as described in the sysreg file, is pretty horrible
as it diesctly give the ESR value. Repaint it using the usual NI/IMP
identifiers to describe the absence/presence of FEAT_IDST.
Also add the new EL3 routing feature, even if we really don't care about it.
