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.
