drm/sysfb: simpledrm: Improve panel-size validation

Validate the panel size from the device-tree node against the
limitations of struct drm_display_mode. The type only stores sizes
in 16-bit fields. Fail transparently on errors; do not warn.

v3:
- move comments to a more prominent place (Thierry)
v2:
- only use initialized values in debugging output (Sashiko)
