At some point back in 2018 prior_stage_fdt_address and OF_PRIOR_STAGE got
introduced, in order to support a DTB handed over by an earlier stage boo
loader. However we have another option in the Kconfig (OF_BOARD) which has
identical semantics.
So let's remove the option in an effort to simplify U-Boot's config and DTB
management, and use OF_BOARD instead.
