ASoC: rt5645: Fix the electric noise due to the CBJ contacts floating

Browse source

The codec leaves tie combo jack's sleeve/ring2 to floating status
default. It would cause electric noise while connecting the active
speaker jack during boot or shutdown.
This patch requests a gpio to control the additional jack circuit
to tie the contacts to the ground or floating.
