DTS: Provide USB host DTS description for i.MX53 devices

This code has been ported from Linux kernel - tag v5.1-rc2.
The difference from the kernel is the removal of:
fsl,usbmisc = <&usbmisc 1>;
fsl,usbphy = <&usbphy1>;

properties, which are not needed for correct u-boot operation (as PHY
setup is done in ehci-mx5.c file itself).
