scw 32bd2f7d95 Add a heuristic to test if an audio CODEC's AC97_REG_POWER register supports 
the AC97_POWER_ANL bit.

The heuristic simply checks if AC97_REG_POWER's AC97_POWER_MIXER  bit can
be set, implying the CODEC can control power to its mixer. If the bit
reads back as zero after we set it, assume ANL is reserved.

Without this patch, some CODECs (e.g. Philips UCB1400) will experience long
delays during attach and resume while the driver waits for a bit which will
never set.

Thanks to jmcneill@ for reviewing this WRT AC97 modem power control.
