Subject: [PATCH 3/3] arm64: dts: sdm845: move gpu zap nodes to per-device dts

From: Rob Clark <robdclark@...omium.org>

We want to specify per-device firmware-name, so move the zap node into
the .dts file for individual boards/devices.  This lets us get rid of
the /delete-node/ for cheza, which does not use zap.
