conf: machine: imx8m: correct tune for mainline bsp

Mainline BSP does not contain imx8m in machine overrides, which causes
generic tunes to be set for i.MX8M derivates, rather than a more precise
tune which enables crypto extension. Those extensions are enabled in NXP
BSP due to those settings rely on machine overrides.

Adapt tunes for Mainline BSP in machine include files to include crypto
extensions and align it with NXP BSP.
