ARM: dts: da850-lcdk: Update DTS files for SPL device tree support

Currently, the da850-lcdk uses SPL_OF_PLATDATA and manually loads
the necessary source code instead of using the auto-generated,
because the drivers don't properly autogenerate the code.

This patch simply enables the various device tree options to
mimic the da850-evm which doesn't need or use OF_PLATDATA for
device tree support.  It does not disable OF_PLATDATA.
