imx: imx8: Update README with somewhat correct firmware versions 

Current setup instructions for i.MX8QM MEK board include somewhat
conflicting instructions, so here's an attempt to fix it.

After trying both sets of firmwares, I can conclude that both of
them fail to work:

- no boot at all with imx-sc-firmware-0.7 / firmware-imx-7.6

- partial success with imx-sc-firmware-1.1 / firmware-imx-8.0:
