regulator: gpio-regulator: Fix finding of smallest value
Commit 4dbd8f63f07a (regulator: gpio-regulator: Set the smallest
voltage/current in the specified range) forgot to set the newly
introduced best_val.
Therefore it stayed always at INT_MAX thus breaking the setting
of the voltage.
Included is also an init value for target, as warnings about
a possibly uninitialised target started appearing with this fix.
