ARM: dts: msm: Add GPU PIL for Zap shader on msmtitanium 



GPU uses a zap shader ucode to flush internal memories when
switching from trusted to untrusted mode. This ucode needs to be
protected and programmed by the TZ. We use the PIL to do
the appropriate calls to the TZ for us and it needs a DT node
to recognize what needs to be loaded.
