Subject: [PATCH 5.4 011/102] ARM: dts: logicpd-torpedo-37xx-devkit-28: Reference new DRM panel

From: Adam Ford <aford173@...il.com>

commit a177057a95f6a3f1e0e52a17eea2178c15073648 upstream.

With the removal of the panel-dpi from the omap drivers, the
LCD no longer works.  This patch points the device tree to
a newly created panel named "logicpd,type28"

Fixes: 8bf4b1621178 ("drm/omap: Remove panel-dpi driver")
