[Buildroot] [git commit] board/freescale/common/imx: add support for i.MX8MM

[Arnout Vandecappelle (Essensium/Mind)]

commit: https://git.buildroot.net/buildroot/commit/?id=92ac758c40f80487362b69db955564fdaaa05827
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

For the boot image creation for the i.MX8MM, the main differences with
i.MX8M are that there is no HDMI firmware image passed, and the ATF
load address is different.
