[PATCH] i.MX chipidea support

[Sascha Hauer]

The following adds support for the chipidea core of the i.MX SoCs.
It is somewhat designed after the kernel chipidea driver. A usb-misc
driver matches to the misc registers and allows a driver which binds
to the usb devices themselves to configure the misc registers. If ULPI
support is selected, the ULPI phy will be configured automatically.
This is done to simplify the board code for USB. Currently no support
for USB device is available, that could be added later. This series
also contains a patch which allows it to register a EHCI HCD without
matching to a device, which is needed for the chipidea support.
