    drivers/gic: reprogram the GIC CPU interface to bypass IRQ
    
    GICv2 provides a wake IRQ/FIQ (for wake-event purpose), which are not
    disabled by GIC CPU interface. This is done by adding a bypass override
    capability when the interrupts are disabled at the CPU interface. To
    support this, there are four bits about IRQ/FIQ BypassDisable in CPU
    interface Control Register. So the CPU can exit from WFI when an
    asserted IRQ is coming. This is critical for power gating a CPU.
    
    BRANCH=none
    BUG=chrome-os-partner:39620
    TEST=testing with CPU idle with power down state support and CPU can
         wake up normally
