app: boards: Add overlays for i.MX8QM and i.MX8QXP

This commit is needed because the current Linux kernel version used in our internal testing doesn't contain the patches that enable MU2's power. As such, to avoid failures in the internal tests, disable the CCM and LPUART2 IPs. Signed-off-by: Laurentiu Mihalcea <[email protected]>
