[0/3] Remove the USB EP configuration from device tree

Hello,

The Atmel USB device controller is the only one having the description
of the End Point configuration in the device tree.

This configuration depend on the version of the controller used in the
SoC. This variation is already documented by the compatible string of
the controller.

In this series the configuration is associated to the compatible
string which allows to remove the EP child node from the device
tree. The main benefit of it, beyond the simplification of the device
tree, is the reduction of the size of the dtb which was too big to be
managed by the bootloader.

The first two patches should be merged through the USB subsystem while
the last one should be take by the a91 subsystem. Moreover this last
patch should be merged only once the change in the driver is merged.

Gregory
