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.
