[PATCH v4 5/5] KVM: selftests: arm64: Use is_aarch32_id_reg() in test_vm_ftr_id_regs()

[Mark Brown]

test_vm_ftr_id_regs() uses a simplified check for 32 bit ID registers since
it knows it will only run on ID registers. For clarity update this to use
the newly added is_aarch32_id_reg(), there should be no functional change.
