regulator: anatop: set default voltage selector for pcie
Set the initial voltage selector for vddpcie in case it's disabled
by default.
This fixes the below warning:
20c8000.anatop:regulator-vddpcie: Failed to read a valid default voltage selector.
anatop_regulator: probe of 20c8000.anatop:regulator-vddpcie failed with error -22
