MediaTek platforms may need the MTU3 controller before U-Boot proper is
available, but the driver is currently selected and built only with the
main U-Boot configuration symbols.
Add an explicit SPL controller option with host and gadget modes. Make
the driver build and its role checks phase-aware so each phase can select
the MTU3 role it needs without coupling it to the U-Boot proper controller
configuration.
The upstream binding locates the xHCI child registers through the parent
ranges property. Select SPL_OF_TRANSLATE for host mode so SPL can resolve
that address before mapping it.
