task #25552995

commit d98d0a990ca1446d3c0ca8f0b9ac127a66e40cdf upstream

The values non secure EL1 needs to use for PMR and RPR registers depends on
the value of SCR_EL3.FIQ.

The values non secure EL1 sees from the distributor and redistributor
depend on whether security is enabled for the GIC or not.

To avoid having to deal with two sets of values for PMR
masking/unmasking, only enable pseudo-NMIs when GIC has non-secure view
of priorities.

Also, add firmware requirements related to SCR_EL3.
