Accessing the AFSR1_EL3

Accesses to this register use the following encodings:

MRS <Xt>, AFSR1_EL3

op0op1CRnCRmop2
0b110b1100b01010b00010b001

if PSTATE.EL == EL0 then UNDEFINED; elsif PSTATE.EL == EL1 then UNDEFINED; elsif PSTATE.EL == EL2 then UNDEFINED; elsif PSTATE.EL == EL3 then return AFSR1_EL3;

MSR AFSR1_EL3, <Xt>

op0op1CRnCRmop2
0b110b1100b01010b00010b001

if PSTATE.EL == EL0 then UNDEFINED; elsif PSTATE.EL == EL1 then UNDEFINED; elsif PSTATE.EL == EL2 then UNDEFINED; elsif PSTATE.EL == EL3 then AFSR1_EL3 = X[t];
