Subject: [PATCH 1/3] drm/panel: ltk050h3146w: add mipi_dsi_device.mode_flags to of_match_data

From: Quentin Schulz <quentin.schulz@...obroma-systems.com>

To prepare for a new display to be supported by this driver which has a
slightly different set of DSI mode related flags, let's move the
currently hardcoded mode flags to the .data field of of_device_id
structure.
