Subject: [PATCH v4 14/14] KVM: arm64: selftests: Teach get-reg-list about
 FPMR

FEAT_FPMR defines a new register FMPR which is available at all ELs and is
discovered via ID_AA64PFR2_EL1.FPMR, add this to the set of registers that
get-reg-list knows to check for with the required identification register
depdendency.
