MA-12939: drm/imx/dcss: check source plane size

DCSS has some minimum requirements for the source buffer size that need
to be respected in order to not freeze DPR and/or scaler.

This patch will add the checks and return an error if source plane size
is not allowed. Userspace will need to gracefully handle this.
