Merge branch 'pci/controller/imx'

- Replace variant switches with drvdata clock descriptions and clk_bulk API
  (Frank Li)

- Replace variant switches with drvdata PHY flag for devm_phy_get() (Frank
  Li)

- Replace variant switches with drvdata HAS_RESET flags for handling resets
  (Frank Li)

- Replace variant switches with drvdata for LTSSM control bits (Frank Li)

- Replace variant switches with drvdata for controller Root Complex vs
  Endpoint modes (Frank Li)

- Replace variant switches with drvdata .init_phy() callback pointers
  (Frank Li)

- Drop dt-binding redundant duplicate clock check (Frank Li)

- reg/reg-name (Frank Li)

- Drop addr_space retrieval code since dw_pcie_ep_init() already does it
  (Frank Li)

- Add epc_features to drvdata (Frank Li)

- Add iMX95 Root Complex and Endpoint support and dt-binding compatible
  strings (Frank Li)

* pci/controller/imx:

  PCI: imx6: Simplify switch-case logic by introducing init_phy() callback
  PCI: imx6: Simplify configure_type() by using mode_off and mode_mask
  PCI: imx6: Simplify ltssm_enable() by using ltssm_off and ltssm_mask
  PCI: imx6: Simplify reset handling by using *_FLAG_HAS_*_RESET
  PCI: imx6: Simplify PHY handling by using IMX6_PCIE_FLAG_HAS_PHYDRV
  PCI: imx6: Simplify clock handling by using clk_bulk*() function
