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.
