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.
