ALSA: hda - Add keycode map for alc input device
Then users can remap the keycode from userspace. If without the remap,
the input device will pass KEY_MICMUTE to userspace, but in X11 layer,
it uses KEY_F20 rather than KEY_MICMUTE for XF86AudioMicMute. After
adding the keycode map, users can remap the keycode to any value users
want.
