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. Signed-off-by: Takashi Iwai <tiwai@suse.de>
