The GPU on X1E80100 requires ZAP 'shader' file to be useful. Since the
file is signed by the OEM keys and might be not available by default,
disable the GPU node and drop the firmware name from the x1e80100.dtsi
file. Devices not being fused to use OEM keys can specify generic
location at `qcom/x1e80100/gen70500_zap.mbn` while enabling the GPU.
