KVM: arm64: Fix FGT mapping for HFGITR_EL2.nGCSEPP

Browse source

The encoding to trap mapping currently maps a FGT on OP_GCSPOPX to
HFGITR_EL2.nGCSEPP but as per DDI0601 2026-06 this FGT controls trapping
of GCSPUSHX and GCSPOPCX, and not the separate GCSPOPX instruction.
Update the mapping to reflect the architecture.
