For completeness: It seems this approach is not going to be used after
all. The approach (not this particular patch) was conceived to get ehci
support on ramips, but now that echi also sets a default mask and it
turns out that the other setup needed is best done through a phy device,
this approach is probably not needed anymore for ehci. For dwc2, I guess
it should also set up a dma_mask like ehci does (at least until we sort
out this thread) :-)

Gr.
