sandbox: Update dts files to reduce SPL size

At present there are require a few devices in the devicetree which are
not actually used in SPL. This will cause problems with the new
of-platdata, since it will try to instantiate devices which are not
compiled into U-Boot.

Update the devicetree to remove these devices from SPL.
