ALSA: hda - Add a fixup for HP Folio 13 mute LED
commit 37c367ecdb9a01c9acc980e6e17913570a1788a7 upstream.
HP Folio 13 may have a broken BIOS that doesn't set up the mute LED
GPIO properly, and the driver guesses it wrongly, too. Add a new
fixup entry for setting the GPIO pin statically for this laptop.
