ALSA: hda/realtek - The Mic on a RedmiBook doesn't work

BugLink: https://bugs.launchpad.net/bugs/1896828
commit fc19d559b0d31b5b831fd468b10d7dadafc0d0ec upstream.

The Mic connects to the Nid 0x19, but the configuration of Nid 0x19
is not defined to Mic, and also need to set the coeff to enable the
auto detection on the Nid 0x19. After this change, the Mic plugging
in or plugging out could be detected and could record the sound from
the Mic.

And the coeff value is suggested by Kailang of Realtek.
