USB: Add support for Xilinx USB host controller
Add bus glue driver for Xilinx USB host controller. The controller can be configured as HS only or HS/FS hybrid. The driver uses the device tree file to configure the driver according to the setting in the hardware system. This driver has been tested with usbtest using the NET2280 PCI card.

+ The Xilinx USB host controller is EHCI compatible but with a different
+ base address for the EHCI registers, and it is always a big-endian
+ USB Host controller. The hardware can be configured as high speed only,
+ or high speed/full speed hybrid.
+ Required properties:
+ - xlnx,support-usb-fs: A value 0 means the core is built as high speed
