verdin-imx95: add reg_dsi_lvds for use by the touch controllertoradex_6.6-2.2.x-imx
On Dahlia, SLEEP_MOCI will go low during suspend, removing power from
the DSI to LVDS bridge and touch controller. When resuming the system,
touch no longer works.
Specify the dependency of the touch controller on SLEEP_MOCI via
reg_dsi_lvds.
