PCI: qcom: Add support for IPQ9574

Add the new IPQ9574 platform which is based on the Qcom IP rev. 1.27.0
and Synopsys IP rev. 5.80a.

The platform itself has four PCIe Gen3 controllers: two single-lane and
two dual-lane, all are based on Synopsys IP rev. 5.70a. As such, reuse
all the members of 'ops_2_9_0'.
