The codec reset pin is connected to several peripherals. When the
reset is released, unfortunately the ADV7171 powers itself up rather
than remaining in power-down mode. As we don't have a driver for
this device, we end up needlessly consuming an additional 330mW.
Not only that but we should have a way to arbitrate the reset signal.
This patch provides that facility: we program the ADV7171 to sleep
mode whenever the reset is released, and we release the reset when
any one of the three peripherals requests the reset to be released.

Convert Assabet socket driver to use the new irq/gpio management.
This is slightly more involved because we have to touch the private
platform header file to modify the GPIO bitmasks to be GPIO numbers.
