cleanup: Consolidate power interrupts

Browse Source 
Every chipset had its own header file just to declare a GPIO interrupt
handler.  Since this seems to be a common feature of the power
interface, make a standard power_interrupt() API provided by
chipset.h.  This lets us get rid of 4 include files, and makes it
easier to add more chipsets in the future.
