With the commit 4fcba5d556b4 ("regulator: implement basic reference
counter") the return value of regulator_set_enable may be EALREADY or
EBUSY for fixed/gpio regulators and may be further expanded on all
regulators.
Change to use the more relaxed regulator_set_enable_if_allowed to
continue if regulator already was enabled or disabled.
