Recent patches declares board_usb_init function prototype for a new
usb architecture.
Turning on the OMAP_XHCI defines cause a redefinition compiler failure.
So update the board_usb_init to the latest prototype.

Moving the usb/phy code from xhci-omap to the usb/phy directory
and moving the associated phy code over to the new file.
Newer TI processors adding xHCI support will have different PHY configurations
so therefore abstracting this code away will prevent messing around with the
xhci-omap file itself.

Add the support for the dra7xx xhci usb host.
dra7xx does not contain an EHCI controller so the headers
can be removed from the board file.
The xHCI host on dra7xx is connected to a usb2 phy so need to
add support to enable those clocks.

Move the MAC creation from the USB init to an function
that is called on every boot. This will then populate the
usbethaddr mac that kernel driver can pick up from the
device tree blob.
