arm64: dts: qcom: sdm845: remove snps,dw-pcie compatibles

On SDM845 PCI controller bindings are not compatible with snps,dw-pcie
binding. The platform doesn't provide second (global) IRQ, it requires
additional glue code. To prevent it from probing against the dw-pcie
driver, remove corresponding compatible.
