Subject: [PATCH] ALSA: hda/realtek: Enable mute LED on HP Laptop 17-cn2xxx

The HP Laptop 17-cn2xxx (subsystem ID 0x103c899b) uses the ALC236
codec and controls the mute LED via COEF 0x07 index 1, the same
mechanism as the other HP consumer laptops (15s-eq1xxx, 14-fq0xxx,
15-gw0xxx). No existing quirk covers this subsystem ID, so the mute
LED stays off when the system is muted.

Add a quirk entry to enable the mute LED.
