MFD: ucb1x00-core: fix gpiolib direction_output handling
gpiolib drivers should first set the output data before setting the
direction to avoid putting glitches on an output signal. As an
additional bonus, we tweak the code to avoid unnecessary register
writes to the output and direction registers if they have no need
to be updated.
