ALSA: hda/realtek - Enable micmute LED on and HP system

[ Upstream commit 3e0650ab ]

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.
