usb: dwc3-meson-g12a: Use regulator_set_enable_if_allowed

Some meson targets are using a fixed regulator about usb.
It's always returning to EALREADY, so driver doesn't init fine.
To prevent this problem, use the regulator_set_enable_if_allowed
instead of regulator_set_enable.

Fixes: 4fcba5d556b ("regulator: implement basic reference counter")
