[U-Boot] [PATCH 3/4] ODROID-XU3: Make odroid-xu3 an smdk5420 variant

The odroid-xu3 board file sets up clocks that should have are setup by
the SPL/BL2, so that code should be redundant. Drop it and make the XU3
an smdk5420 variant like e.g. Peach pit/pi, that way the only
differences in the boards u-boot binary are purely due to configuration
changes, not code differences.
