Log Message:
Improve detection of NS vs S views of priorities.

For PMR, write a 0 to bit7 and see if it sticks. This is only possible from
NS EL1 if we have a non-secure view of ICC_PMR_EL1.

For int priorities (GICD/GICR interfaces and LPIs), assume that the
GICD_CTLR.DS bit is telling us the truth.

RK3399 is special here when using the vendor bootloader, so keep the
auto-detection from the previous commit but limit the scope to only run
on RK3399 SOCs.
