arm64: dts: qcom: sc7280: don't enable GPU on unsupported devices

On SC7280 and derivative platforms GPU by default requires a signed
binary, a660_zap.mbn. Disable GPU by default and enable it only when
the binary is actually available (QCM6490-IDP, RB3gen2). ChromeOS
devices do not use TrustZone, so GPU can be enabled by default in
sc7280-chrome-common.dtsi. FairPhone5 and SHIFTphone8 DTS already
enable GPU (even though it wasn't required beforehand).
