With binman generating flash.bin, it's not longer necessary to specify either the location of ATF nor is it necessary to specify building flash.bin, so let's update the build instructions to remove those. While in here, update the revision of ATF and DDR firmware so both Mini and Nano reference the same revision.

Perhaps, it's better to advise the [lf-5.10.72-2.2.0] tag here instead of branch?

There is a newer version of DDR firmware available from NXP (8.14), perhaps you can recommend it here instead of 8.9.

I don't think anything about the DDR firmware actually changed in a long time. There are other parts within that firmware-imx package which did change. However, they are irrelevant for U-Boot.
