phycore-imx8mp: Add overlay and bootenv.txt support
Add support for loading bootenv.txt as well as loading and applying
overlays during boot from mmc and net.
${no_bootenv}: Prevent loading external bootenv.txt environment. Use
${overlays} variable directly from u-boot environment.
${no_overlay}: Do not load overlays defined in ${overlays} variable.
Overlays loaded over the extension command are still
being applied.
