proximity: vl53l0x: Make VDD regulator actually optional

Contrary to what the naming might suggest, devm_regulator_get_optional
returns -ENODEV in case the regulator is not found which will trigger
probe error in this driver.

Use devm_regulator_get instead which will return a dummy regulator that
we can just use as if it was a proper regulator.
