Handle IRQ from TPS65090, pass AC status to AP
Changes made by this patch:
1. Create IRQ handler for the TPS65090 IRQ. IRQ wakes up charger task.
2. Charger task sets the AC_STATUS GPIO based on the AC status.
3. Initialize PMU at power-on.
BRANCH=snow
BUG=chrome-os-partner:11739
TEST=Power on the system, with servo v2 connected to EC console. Plug
and unplug AC. The IRQ handler should be triggered.
