The HP Z66 G6 14 inch laptop uses the ALC236 codec with subsystem ID
0x103c:8df7. Without a quirk entry, the PCI SSID falls back to the
generic 0x103c:0000 fixup, which does not configure the mute/micmute
LED GPIOs correctly.

Add the SND_PCI_QUIRK entry for this model using
ALC236_FIXUP_HP_GPIO_LED, matching the surrounding HP EliteBook G12
entries (0x8dec-0x8dfe) which share the same ALC236 codec and GPIO LED
layout.
