Subject: [PATCH 04/15] arm64: dts: imx8mm-phycore-som: Assign regulator for dsi to lvds bridge

From: Yashwanth Varakala <y.varakala@...tec.de>

Add a missing voltage regulator of 1.8v to the sn65dsi83
(dsi_lvds bridge) node. Due to the absence of this regulator, a fallback
dummy regulator is used and that triggers a warning message from the
kernel. Assigning the appropriate regulator avoids the warning.
