ALSA: hda - Fix Internal Mic boost can't control with ALC283
ALC283 pin control for Line1 default control by hidden register. Use line1 as internal Mic will not get sound when boost value up. Set control by verb for hidden register will solve this issue. Signed-off-by: Kailang Yang <kailang@realtek.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
