regulator: wm8350: Use wm8350_ldo_list_voltage instead of open code to verify selected voltage

Call wm8350_ldo_list_voltage() instead of open code to verify selected voltage
falls within specified range.
Use wm8350_ldo_list_voltage() here is less error prone.

wm8350_ldo_val_to_mvolts() is only used in wm8350_ldo_list_voltage now, so
remove it and move the implementation to wm8350_ldo_list_voltage().

This patch also include below small changes in wm8350_ldo_map_voltage:
1. wm8350_ldo_map_voltage() returns selector, thus rename variable mV to sel.
2. Use DIV_ROUND_UP macro to calculate selector.
