Subject: [PATCH 4.19 015/131] ALSA: hda/realtek - Enable micmute LED on and HP system

From: Kai-Heng Feng <kai.heng.feng@...onical.com>

[ Upstream commit 3e0650ab26e2010ee312311612e40e076ed1feca ]

Though the system uses DMIC, headset mic still uses the HDA, let's use
GPIO 0x1 to control the micmute LED.

The micmute LED GPIO has a different polarity to the mute LED GPIO, we
can use the newly added micmute_led_polarity to indicate that.
