The Legacy-IRQ bypass disable and Legacy-FIQ bypass disable is a
feature of GIC-400 and its not X-Gene specific. The only difference in X-Gene
is that we use PPI31 (Legacy-IRQ) for timer and PPI28 (Legacy-FIQ) for perf

The only time those bits are touched are when the dts is modified with the
bypass flag. Otherwise those bits remain

The GIC-400 implementation allows for FIQ and IRQ bypass. In the
X-Gene implementation, the FIQ bypass must be enabled at all time.
Otherwise, some PPI will appear as FIQ and cause kernel problem.
