hayabusa: partial revert of board update

the board update from an older build branch of Sony was causing
regressions (namely a non functioning touchscreen and vol keys)
possible due to the "touch_vdd" getting ommitted from regulator

i am reverting some of the most obvious changes that could have
caused these issues.
