ALSA: hda - Add patch module option
Added the patch module option to apply a "patch" as a firmware to modify pin configurations or give additional hints to the driver before actually initializing and configuring the codec. This can be used as a workaround when the BIOS doesn't give sufficient information or give wrong information that doesn't match with the real hardware setup, until it's fixed statically in the driver via a quirk.
