[PATCH] drm/mipi-dsi: docs: Mark mipi_dsi_compression_mode() as deprecated

The mipi_dsi_compression_mode() function is a thin wrapper around
mipi_dsi_compression_mode_ext(), which is already marked as deprecated.
Additionally, the non-deprecated mipi_dsi_compression_mode_multi()
alternative exists.

Document this deprecation to encourage developers to use the multi variant.
