This series adds the relavent DT bindings, new compatible string,
add support to EPF driver and add EP PCIe node in dtsi file for
ep pcie0 controller.

v6 -> v7:
- add reviewed by tag in commit message in all patches.
- update commit message in patch 2 as per comment.
- update reason for reusing PID in commit message.

v5 -> v6:
- update cover letter.

v4 -> v5:
- add maxItems to the respective field to constrain io space and
  interrupt in all variants.

v3 -> v4:
- add maxItems field in dt bindings
- update comment in patch2
- dropped PHY driver patch as it is already applied [1]
- update comment in EPF driver patch

v2 -> v3:
- removed if/then schemas, added minItems for reg,
  reg-bnames, interrupt and interrupt-names instead.
- adding qcom,sa8775p-pcie-ep compitable for sa8775p
  as we have some specific change to add.
- reusing sm8450's pcs_misc num table as it is same as sa8775p.
  used appropriate namespace for pcs.
- remove const from sa8775p_header as kernel test robot
  throwing some warnings due to this.
- remove fallback compatiable as we are adding compatiable for sa8775p.

v1 -> v2:
- update description for dma
- Reusing qcom,sdx55-pcie-ep compatibe so remove compaitable
  for sa8775p
- sort the defines in phy header file and remove extra defines
- add const in return type pci_epf_header and remove MHI_EPF_USE_DMA
  flag as hdma patch is not ready
- add fallback compatiable as qcom,sdx55-pcie-ep, add iommu property
