usb: uhci-platform: Make the clock really optional
Device tree bindings state that the clock is optional for UHCI platform
controllers, and some existing device trees don't provide those - such
as those for VIA/WonderMedia devices.
The driver however fails to probe now if no clock is provided, because
devm_clk_get returns an error pointer in such case.
Switch to devm_clk_get_optional instead, so that it could probe again
on those platforms where no clocks are given.
