AC97 reset is broken on the pxa27x.  These patches fix it by addressing multiple
  - cold reset fails because the GCR register is not set correctly
  - warm reset fails because some code used to work around a hardware bug is
  - the intent of the work-around code is obfuscated by unfortunate function

This patch set replaces some earlier individual patches that had some problems.
Thanks Robert and Igor.
