There exists non-bridge PCIe devices with PCI_VENDOR_ID_QCOM, so limit the fixup to only affect the relevant PCIe bridges.

Hi Bjorn,
to simplify stable's merging, would you mind helping me with the stable releases you want this patch to apply to please ?
We've to have this in the patch:
Cc: stable@vger.kernel.org # v5.2+ Fixes: 322f03436692 ("PCI: qcom: Use default config space read function")
I will apply it then.
Thanks, Lorenzo

Stan, I picked up all the suggested device id's from the previous thread and added 0x1000 for QCS404. I looked at creating platform specific defines in pci_ids.h, but SDM845 has both 106 and 107... Please let me know if you would prefer that I do this anyway.
