mb/lenovo/t420: Copy HDA verbs from vendor firmware
Background story (I think that's what great in opensource -
ppl leave there part of their lives): ;-)
While trying to fix audio jack not working with coreboot and
Windows 10 with some help from hell__ and nico_h on IRC nico_h
discovered that t420 and t430 hda_verb.c are the same:
<nico_h> oddly, in coreboot source T420 and T430 have the same
numbers for very different codecs... I suspect copy-pasta
Difference between /sys/class/sound/cardX/hwCXDY/init_pin_config
in vendor BIOS helped with the updated config. Connecting audio
jack now works flawless both in Linux and Windows.
Audio-related keyboard buttons: volup, voldown, mute works fine
both in Linux (Debian-based) and Windows 10. mutemic button works
(tested ie. with xev) but both in Linux and Windows 10 wont light
up or makes any effect.
