ALSA: hda - Reorganize controller quriks with bit flags 

Introduce bit-flags indicating the necessary controller quirks, and
set them in pci driver_data field.  This simplifies the checks in the
driver code and avoids the pci-id lookup in different places.

Also, this patch adds the PCI ID entry for AMD Hudson.  AMD Hudson
requires a similar workaround like ATI SB while other generic ATI and
AMD controllers don't need but some ATI-HDMI quirks.  So, we need a
different entry for Hudson.
