ALSA: hda/realtek: Add inverted LED quirk for HP ZBook 8 G2a
HP ZBook 8 G2a 14 and 16 (SSIDs 0x103c:0x8f94, 0x103c:0x8f95) use the
Realtek ALC245 codec with a TAS2781 amplifier via I2C. They share the same
hardware configuration as the existing 0x8f40/0x8f41/0x8f42/0x8f62 models
but have inverted speaker mute LED polarity, so the existing
ALC245_FIXUP_HP_TAS2781_I2C_MUTE_LED quirk drives the LED backwards: off
when muted and on when unmuted.
Add a dedicated quirk with inverted COEF values. These are speaker-only
models without an HP pin, so the LED is driven directly through the
vmaster_mute hook; there is no need to probe the HP pin at runtime since
the configuration is static and known per SSID.
