PCI: Add MCFG quirks for Qualcomm QDF2432 host controller
The Qualcomm Technologies QDF2432 SoC does not support accesses smaller than 32 bits to the PCI configuration space. Register the appropriate quirk. [bhelgaas: add QCOM_ECAM32 macro, ifdef for ACPI and PCI_QUIRKS] Signed-off-by: Christopher Covington <cov@codeaurora.org> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
