This changes the virt target so that it can be run with the -bios option
and a pflash backend for the flash. QEMU can now be run as follows:
qemu -M virt -m 1G -nographic -bios build/coreboot.rom \
-drive if=pflash,file=./build/coreboot.rom,format=raw
coreboot will start in DRAM, but still have a flash to put CBFS onto and
to load subsequent stages and payload from.
Tested bootflow:
coreboot -> OpenSBI -> Linux -> u-root
