Subject: [PATCH 2/2] drm/panel: ltk050h3146w: drop duplicate commands from LTK050H3148W init

From: Heiko Stuebner <heiko.stuebner@...rry.de>

The init sequence specifies the 0x11 and 0x29 dsi commands, which are
the exit-sleep and display-on commands.

In the actual prepare step the driver already uses the appropriate
function calls for those, so drop the duplicates.

Fixes: e5f9d543419c ("drm/panel: ltk050h3146w: add support for Leadtek LTK050H3148W-CTA6 variant")
