[PATCH v4 6/8] arm: dts: qcom: stop using snps,dw-pcie falback

Qualcomm PCIe devices are not really compatible with the snps,dw-pcie.
Unlike the generic IP core, they have special requirements regarding
enabling clocks, toggling resets, using the PHY, etc.

This is not to mention that platform snps-dw-pcie driver expects to find
two IRQs declared, while Qualcomm platforms use just one.
