DT && i.MX USB

[Alexander Shiyan]

Hello.

I am trying to migrate i.MX51 ConnectCore board for use DT.
Most stuff are done but I cannot understand how USB subsystem
works with devicetree.

First, why barebox uses own "barebox,dr_mode" and "barebox,phy_type"
properties instead of use kernel "dr_mode" and "phy_type"?

Second, how specify flags for USB ports, for example MXC_EHCI_INTERNAL_PHY?
In DT case we can not do it and as result desired port not functional...

Thanks.
