[ 025/123] ALSA: hda - add mute LED for HP Pavilion 17 (Realtek codec)

From: David Henningsson <david.henningsson@canonical.com>

commit 6d3cd5d444223c41eabb70dccff14fae4e8cb8b1 upstream.

The mute LED is in this case connected to the Mic1 VREF.

The machine also exposes the following string in BIOS:
"HP_Mute_LED_0_A", so if more machines are coming, it probably
makes sense to try to do something more generic, like for the
IDT codec.
