Subject: [PATCH RFC v2 0/5] Add support for Saef SFTO340XC panel.

Add support for Saef Technology Limited SFTO340XC LCD panel.
Add alongside the number of lanes configuration in the ili9881c driver
as the board on my desc use the panel with only two lanes.

Faced an issue with panel-common binding. Wrote a fix (first patch) but not
sure it is the right one. If someone from dt tree could take a look, it
would be nice.

Changes in v2:
- Add new patch trying to fix panel-common binding.
- Read the data-lanes parameter from the port endpoint and use
  drm_of_get_data_lanes_count instead of of_property_read_u32.
- Link to v1: https://lore.kernel.org/r/20250408-feature_sfto340xc-v1-0-f303d1b9a996@bootlin.com
