Subject: [RFC 3/3] arm64: dts: qcom: sdm845-cheza: delete zap-shader

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

This is unused on cheza.  Delete the node to get rid of the reserved-
memory section, and to avoid the driver from attempting to load a zap
shader that doesn't exist every time it powers up the GPU.
