This adds the UUU UCmd functionality as an OEM command. While the fastboot tool allows sending arbitrary commands as long as they are prefixed with "oem". This allows running generic U-Boot commands over fastboot without UUU, which is especially useful when not using USB. This is really the route we should have gone in the first place when adding these commands. While we're here, clean up the UUU Kconfig a bit.
