doc: qemu-riscv: Update QEMU run command
Explicitly pass the "-bios" option to QEMU to run U-Boot, instead of the "-kernel" option, as we know that "-bios" behavior will be changed since QEMU 5.1.0. This also updates validated QEMU version to 5.0.0. Signed-off-by: Bin Meng <bin.meng@windriver.com> Reviewed-by: Atish Patra <atish.patra@wdc.com>
