pico-imx6ul, pico-imx7d: Explain how to use eMMC user partition 

The default U-Boot environment expects the use of eMMC user
partition. To ensure we are using the proper eMMC partition for boot
we need to run the `mmc partconf` command.

This patch updates the README instructions to avoid users to follow
misleading instructions.
