ALSA: hda: Allow non-Intel device probe gracefully

Browse Source 
The recent addition of snd_intel_dsp_driver_probe() check caused a
spurious kernel warning when the driver is loaded for a non-Intel
hardware due to snd_BUG_ON().  Moreover, for such a hardware, we
should always return SND_INTEL_DSP_DRIVER_ANY, not check the
dsp_driver option at all.

This patch fixes these issues for non-Intel devices.
