[PATCH v2 3/3] riscv: Enable CONFIG_OF_BOARD_FIXUP by default

[Bin Meng]

From: Bin Meng <bin.meng at windriver.com>

Starting from OpenSBI v0.7, the SBI firmware inserts/fixes up the
reserved memory node for PMP protected memory regions. All RISC-V
boards needs to copy the reserved memory node from the device tree
provided by the firmware to the device tree used by U-Boot.

Turn on CONFIG_OF_BOARD_FIXUP by default.
