[Buildroot] [PATCH] configs/imx8mqevk_defconfig: new defconfig

[Fabio Estevam <festevam@gmail.com>]

Add support for imx8mqevk_defconfig that allows booting a mainline
kernel.

This defconfig still relies on NXP ATF and U-Boot, but in the long term
the plan is to switch to mainline ATF and U-Boot as well.

Hi,

There was an attempt from Xavier to allow generating a Buildroot
image with mainline U-Boot for i.MX8M:
http://lists.buildroot.org/pipermail/buildroot/2020-July/287144.html

As this effort seems to have stalled, let's a give the first step and
use mainline kernel only for now.
