[ Upstream commit 2f388b4e8fdd6b0f27cafd281658daacfd85807e ]

The HP Pavilion 15-eg0xxx with subsystem ID 0x103c87cb uses a Realtek
ALC287 codec with a mute LED wired to GPIO pin 4 (mask 0x10). The
existing ALC287_FIXUP_HP_GPIO_LED fixup already handles this correctly,
but the subsystem ID was missing from the quirk table.

GPIO pin confirmed via manual hda-verb testing:
  hda-verb SET_GPIO_MASK 0x10
  hda-verb SET_GPIO_DIRECTION 0x10
  hda-verb SET_GPIO_DATA 0x10
