Subject: [PATCH v2 2/2] PCI: qcom: Add SM8550 PCIe support

Add compatible for both PCIe found on SM8550.
Also add the cnoc_pcie_sf_axi clock needed by the SM8550.

The v1 was here:
https://lore.kernel.org/all/20221116123505.2760397-2-abel.vesa@linaro.org/

Changes since v1:
 * changed the subject line prefix for the patch to match the history,
   like Bjorn Helgaas suggested.
 * added Konrad's R-b tag
