The mpc5200 asoc code did not run after the multi-codec patches. This series
fixes the existing code and adds a generic platform driver that allows the
audio layout to be described in the device tree.

Tighten up time timing around the gpio reset functionality. Add a 200ns
delay before remuxing the pins back to ac97 to comply with the ac97 spec.
This delay ensures that sync and sdata_out are held low while reset
transitions to high.

The implementation of the ac97 "cold" reset is flawed. If the sync and
output lines are high when reset is asserted the attached ac97 device
may go into test mode. Avoid this by reconfiguring the psc to gpio mode
and generating the reset manually.

Allow device drivers to safely modify port-config. This allows device drivers
access to gpio pins to manually bit-bang slave devices.
