because we support U-Boot system suspend and trap into ATF,
we have to make pwrkey as wakeup source, so that we must
register pmic_int as an irq.
we found reading 'get_timer(0)' will return a large value in
the interrupt routine and I don't find out what happend now,
so I add the 'get_ms()' which reads arm gerneric timer tick
direcly.
we clean all PMIC interrupt status for safety to avoid pmic_int
hold in low level which make PMIC can't respond to interrupt any
more.
