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

Same comment as 2/5 -- the priv->vbus_supply check is likely mandatory.
It is not, I made a note of it in the cover letter.

The regulator_set_enable_if_allowed function is more relaxed and will
return ENOSYS if the provided regulator is NULL or when DM_REGULATOR
was disabled. Using the following call convention should be safe:
Thank you for clarifying.
