ID_AA64MMFR0_EL1.TGRAN{4,16,64}_2 are currently represented as unordered enumerations. However, the architecture treats them as Unsigned, as hinted to by the MRS data: (FEAT_S2TGran4K <=> (((UInt(ID_AA64MMFR0_EL1.TGran4_2) == 0) && FEAT_TGran4K) || (UInt(ID_AA64MMFR0_EL1.TGran4_2) >= 2)))) and similar descriptions exist for 16 and 64k. This is also confirmed by D24.1.3.3 ("Alternative ID scheme used for ID_AA64MMFR0_EL1 stage 2 granule sizes") in the L.b revision of the ARM ARM. Turn these fields into UnsignedEnum so that we can use the above description more or less literally.
