- Pass the Qcom Endpoint 4K alignment requirement for outbound windows to
  the EPF core so EPF drivers can use it (Manivannan Sadhasivam)

- Use alignment restriction from EPF core in Qcom EPF MHI driver
  (Manivannan Sadhasivam)

- Add Qcom Endpoint eDMA support by enabling the eDMA IRQ (Manivannan
  Sadhasivam)

- Add Qcom Snapdragon SM8450 support to the EPF MHI driver (Manivannan
  Sadhasivam)

- Use iATU for EPF MHI transfers smaller than 4K to avoid eDMA setup
  latency (Manivannan Sadhasivam)

- Add pci_epc_mem_init() kernel-doc (Manivannan Sadhasivam)
