By the time I created this binding the binding for the kernel was not
mainline, so I decided to use barebox,x to not end up with an
incompatible binding. As the binding made it mainline now we can drop
the "barebox," now.

Could it be that this flag should simply be dropped? According to the
Block diagram (Freescale i.MX53 ref manual v2.1, page 4700) the otg port
is hardwired to the internal utmi phy, so having this configurable makes
no sense.
