linux-toradex-mainline: Lower CMA size percentage on 32-bit SOM
Lower CMA size percentage from 50% to 35% on i.MX 6/6ULL/7 based SOM,
with that the following CMA Memory will be reserved depending on
SKU memory.
| SOM Memory | CMA Memory |
|--- |--- |
| >= 1GiB | 256MiB |
| 512MiB | 192MiB |
| 256MiB | 96MiB |
With this change is possible to have a GPU application and video
playback on low memory SKU, without having allocation failures and
the related OOM killer issues.
No changes on SKU with >= 1GiB memory.
