riscv: Remove OF_PRIOR_STAGE from RISC-V boards
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.
On RISC-V some of the boards pick up the DTB from a1 and copy it in their
private gd_t. Apart from that they copy it to prior_stage_fdt_address, if
the Kconfig option is selected, which is unnecessary.
So let's switch the config option for those boards to OF_BOARD and define
the required board_fdt_blob_setup() for them.
