fdt: Enable OF_HAS_PRIOR_STAGE for most boards with OF_BOARD

Use this new Kconfig instead of OF_BOARD, so we know for sure which boards
obtain their devicetree from a prior stage. Leave sandbox alone since it
does not. Also don't touch xilinx_versal_virt since it does not have a
specific TARGET Kconfig.

This option implies OF_BOARD for now, but with future work standard
passage may be used instead.
