ALSA: hda - Limit codec-verb retry to limited hardwares

The reset of a BUS controller during operations is somehow risky and
shouldn't be done inevitably for devices that have apparently no such
codec-communication problems.

This patch adds the check of the hardware and limits the bus-reset
capability.
