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:
