[PATCH 2/2] regulator: max8952 - fix max8952_set_voltage

[Axel Lin]

In current implementation, vid is declared as u8,
then "vid == -1" is always false, and "vid >= 0" is always true.
Thus change it to s8.

vid is always less than MAX8952_NUM_DVS_MODE in current implementation,
thus remove the cheking for "vid < MAX8952_NUM_DVS_MODE".
