drm/panel: ltk050h3146w: drop duplicate commands from LTK050H3148W init
[ Upstream commit 55679cc22e60e8ec23b2340248389022798416cd ]
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.
