Since OpenSBI commit bf3ef53bb7f5 ("firmware: Enable FW_PIC by default"), OpenSBI runs directly at the load address without any code movement. This causes the SPL version of QEMU 'virt' U-Boot does not boot Linux kernel anymore. In that case, OpenSBI is loaded and runs at 0x81000000, and it creates a 512KiB PMP window from that address. When booting the Linux kernel, moving kernel to its linking address 0x80200000 overlaps the PMP window, and a PMP access failure is raised.
Update SPL_OPENSBI_LOAD_ADDR to load OpenSBI to a safe address.
