Add a SND_PCI_QUIRK entry for the HP Pavilion Laptop 16-ag0xxx
(subsystem 0x103c:0x8cbc, Realtek ALC245). The
ALC245_FIXUP_HP_X360_MUTE_LEDS fixup is already used by the
neighbouring HP Pavilion Aero Laptop 13-bg0xxx (0x103c:0x8cbd);
it chains the master-mute COEF handler with the GPIO mic-mute
LED handler, which is what this machine needs.

Tested on the affected hardware: both the mute and mic-mute key
LEDs respond correctly to the keyboard hotkeys after this change.
