regulator: core: Correct type of mode in regulator_mode_constrain
Every function handling the mode within the regulator core uses an unsigned int for mode, except for regulator_mode_constrain. This patch changes the type of mode within regulator_mode_constrain which fixes several instances where we are passing pointers to unsigned ints then treating them as an int within this function.
