MLK-11561-2 regulator: anatop: set default voltage selector for pcie

The code reads the default voltage selector from its register.
If the default voltage selector is 0 which results in faulty
behaviour of this regulator driver.

This patch sets a default voltage selector for vddpcie-phy if
it is not set in the register.
