[PATCH] imx: imx8: Update README with somewhat correct firmware versions

[Priit Laes]

From: Priit Laes <priit.laes at paf.com>

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:

U-Boot 2021.04-rc3-00135-ge0669a43c8 (Mar 08 2021 - 16:49:08 +0200)
