The AArch64 system registers DACR32_EL2, IFSR32_EL2, SPSR_IRQ,
SPSR_ABT, SPSR_UND and SPSR_FIQ are visible and fully functional from
EL3 even if the CPU has no EL2 (unlike some others which are RES0
from EL3 in that configuration). Move them from el2_cp_reginfo[] to
v8_cp_reginfo[] so they are always present.
