When the connected CODEC is CS4271, the pin is an input and is used to
request an interrupt via the interface. But when the connected CODEC is
CS4218, the pin is an output used to power down CS4218. When CODEC is
AC97 CODEC, this pin is an output used to indicate an Power Management
Event has happened.

Reset: This pin, when low, resets the CS4218 to a known state.
