ARM: dts: msm: cleanup auto generated message in panel dtsi

Panel dtsi files are generated using gcdb xml parser
and parser adds message in the file to indicate file
is auto generated. However, these files are updated
manually when some tags requires update. That conflicts
with message present in dtsi file. This change removes
the message to avoid confusion between manual update vs
auto generation.
