reimplement interrupt controllers following the kernel coding
conventions
propogate set_irq_wake signal from gpio chip to the primary chip
use IRQ_WAKEUP status to control masking and unmasking of interrupts
when entering low-power modes; non-wakeup interrupts are disabled
using with disable_irq, and are re-enabled after wakeup with enable_irq
ODM kit wakeup pads are configured with enable_irq_wake during the
board initialization
move context save & restore for the GPIO and interrupt controllers out
of power-context-t2.c and into their respective drivers; no distinction
is made between LP0 and LP1 context currently; if there is enough of a
performance difference to warrant reintroducing it, this can be done at
a later time.
