[PATCH 1/2] usb: ehci-mx5: Use regulator_set_enable_if_allowed

[Marek Vasut]

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.

Based on 335799b7252a ("usb: dwc2: Use regulator_set_enable_if_allowed")
