FEAT_E2H0 is a formalisation of the existing behaviour of HCR_EL2.E2H being programmable to switch between EL2 host mode and the "traditional" nVHE EL2 mode. This implies at some point we might want to model CPUs without FEAT_E2H0 which will always have EL2 host mode enabled. There are two values to represent no E2H0 systems of which 0b1110 will make HCR_EL2.NV1 RES0 for FEAT_NV systems. For FEAT_NV2 the NV1 bit is always valid.
