[PATCH v2] drm/meson/meson_venc: Relax the supported mode checks

[Carlo Caione]

Relax a bit the supported modes list by including also 480x1920 and
400x1280. This was actually tested on real hardware and it works
correctly.

In particular relax the resolution checks to allow more resolutions like
480x1920 and 400x1280.
---
Changes in v2:
- Lower the hdisplay limit to support 400x1280 as well.
- Link to v1: https://lore.kernel.org/r/20230210-relax_dmt_limits-v1-0-a1474624d530@baylibre.com
