fix(gic): trap GIC access from secure partitions GIC access is prevented from secure partitions (or secondary VMs). Revert part of e879e8768 where GIC system register access is permitted from S-EL1. Now that Hafnium implements the FF-A guidance for interrupt handling in the SPMC, this relaxation is no longer required. A secure partition is meant to use the Hafnium provided interface to handle secure interrupts and managed exit.
