Fix two MSI issues. One to skip PCIE_MSI_INTR0* programming if MSI is
disabled, another to use an address in the driver data for MSI address,
to fix the MSI page leakage during suspend/resume.

Since v4:
  - fix pci-dra7xx.c

Since v3:
  - add Acked-by tag
  - change patch2 commit msg to make it clear
  - map the MSI msg with dma_map_single_attrs() for some platforms
    which either has seperate addrs for dma and phy or has mem access
    limitation for the PCIe.

Since v2:
  - add Acked-by tag
  - use an address in the driver data for MSI address. Thank Ard and Rob
    for pointing out this correct direction.
  - Since the MSI page has gone, the leak issue doesn't exist anymore,
    remove unnecessary patches.
  - Remove dw_pcie_free_msi rename and the last patch. They could be
    targeted to next. So will send out patches in a separate series.

Since v1:
  - add proper error handling patches.
  - solve the msi page leakage by moving dw_pcie_msi_init() from each
    users to designware host

Hi,

can you rebase this series against my pci/dwc branch please ?

Done in v6.

Thanks
