Build: Disable PS test NV counters when PXN is enabled

The PS test NV counters do not work when PXN is enabled, due to the
counters being in the PS ARoT partition and called from the privileged
test code. So, this patch disables them when PXN is enabled so that the
regression tests can be run with PXN enabled.
