fdt: Swap the signature for board_fdt_blob_setup()
This returns a devicetree and updates a parameter with an error code.
Swap it, since this fits better with the way U-Boot normally works. It
also (more easily) allows leaving the existing pointer unchanged.
No yaks were harmed in this change, but there is a very small code-size
reduction.
For sifive, the OF_BOARD option must be set for the function to be
called, so there is no point in checking it again. Also OF_SEPARATE is
defined always.
