[PATCH] input/mfd/ucb1400: move static function from header into core

[Sebastian Andrzej Siewior <bigeasy@linutronix.de>]

it's a little too large for static line.
The ts is currently the only mainline user but Marek Vasut claims that
there is a battery driver in an ARM tree which also needs this function.
