fdtdec: Add weak function to patch U-Boot DT right after fdtdec_setup()
Add weak function which is called right after fdtdec_setup() configured
the U-Boot DT. This permits board-specific adjustments to the U-Boot DT
before U-Boot starts parsing the DT. This could be used e.g. to patch in
various custom nodes or merge in DT fragments from prior-stage firmware.
