This patch increases reset delay from 50 usec to 80 usec for
USB HOST PHY. In order to reset USB HOST PHY controller properly,
a little extra time is required during its reset cycle.

Since early wakeup can be handled in pm so we don't need masking
interrupts of external GIC. When the early wakeup interrupt happens,
PMU(Power Management Unit) ignores WFI instruction. This means that
PC(Program Counter) passed without any changes. This patch can handle
that case by early wakeup interrupt.
