mb/emulation/qemu-riscv: Protect CBFS from payload loader
The virt machine is special as it doesn't emulate flash and it puts the coreboot.rom at start of DRAM. The payload loader doesn't know about CBFS in DRAM and overwrites the CBFS while decompressing payloads, resulting in undefined behaviour. Mark the region as SRAM to make sure the payload won't overwrite the CBFS while decompressing. As payload is always decompressed to DRAM, it wouldn't touch SRAM memory regions.
