ALSA: hda - Add codec bus reset and verb-retry at critical errors

Some machines machine cause a severe CORB/RIRB stall in certain
weird conditions, such as PA access at the start up together with
fglrx driver.  This seems unable to be recovered without the controller
reset.

This patch allows the bus controller reset at critical errors so
that the communication gets recovered again.
