usb: Add Cadence USB3 host and gadget driver
Add support for USB3 host and gadget driver. This is a direct sync of
Linux kernel Cadence USB stack that from v5.4-rc1 release.
Driver has been modified so that it compiles without errors against
U-Boot code base.
Features not required for U-Boot such as scatter-gather DMA and OTG
interrupt handling has been dropped.
