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.

Enable support for two-lane configuration which is done by setting the
LANSEL_SW_EN and LANSEL_SW bits in the Pad Control register.
Use the dsi-lanes device tree parameter to configure the number of lanes.
The default configuration remains set to four lanes.

Add the dsi-lanes property to specify the number of DSI lanes used by the
panel. This allows configuring the panel for either two, three or four
lanes.

Enable support for two-lane configuration which is done by setting the
LANSEL_SW_EN and LANSEL_SW bits in the Pad Control register.
Use the data-lanes device tree parameter to configure the number of lanes.
The default configuration remains set to four lanes.

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
Add the data-lanes property to specify the number of DSI lanes used by the
panel. This allows configuring the panel for either two, three or four
lanes.
At the same time, extend the devicetree example with an endpoint node for
better clarity.

e error is still there. The only way
to not face the error is to use $defs/port-base reference. I don't
really understand the ins and outs, maybe it is a issue from the binding
check tool.
