This change adds vendor hook for gic-v2 resume to allow vendor GIC
enhancement. This is inline with hook present today in irq-gic-v3.c
with one difference that vendor hooks in v2 driver do not pass entire
gic_chip_data struct to vendor module. Instead it passes the required
fields which are irq_domain and the gic dist base to know the wakeup
IRQ reason.
The newly added vendor hook can get invoked by two ways.
1. By registering with syscore ops, .resume method can invoke vendor
hook. This is applicable for cases like suspend-to-ram which
invokes syscore ops.
2. By exporting the gic_v2_resume(), the newly added vendor hook will
get invoked during the first CPU waking up from suspend-to-idle
case.
While at this move android_vh_gic_resume() to gic_v3.h as its specific
to v3 driver.
