[ALSA] PXA27x AC97 warm reset

Browse source 
ARM PXA2XX driver
This patch extends the period of an AC97 warm reset on the PXA27x from
50uS to 500uS. The shorter reset didn't always guarantee that the codec
would wake up.

Changes:-

  o Change pxa27x warm reset period to 500uS
  o Removed double semi-colon.
