For the benefit of the archives: the root issue here is that AC97 reset
has problems working as documented with the SoC CPU being used here so
it is normally done using a GPIO line on the CPU.  Robert is working on
a consumer device for which he doesn't have hardware documentation so is
unable to generate a working reset to the chip.
