usb: dwc2: Use regulator_set_enable_if_allowed

Browse source 
With the commit 4fcba5d556 ("regulator: implement basic reference
counter") the return value of regulator_set_enable may be EALREADY or
EBUSY for fixed/gpio regulators.

Change to use the more relaxed regulator_set_enable_if_allowed to
continue if regulator already was enabled or disabled.
