Subject: [PATCH v4 0/6] mmc: sdhci-cadence: SD6 controller support

Added changes to support SD6 controller on Marvell CN10K SOCs:
- Restructure and reformat the code.
- Add SD6 related operations.
- Support added for MMC_SDHCI_IO_ACCESSORS.
- Related changes done in dt bindings.
- Support for debug option.

Changes since V3:
- Adapted to the new code structure sdhci_cdns_drv_data.
- Added controller version specific phy_init separating SD4 and SD6.
- Added SD6 compatibility check for SD6 specific things like
  quirks/version.
- Added marvell specific string to dts properties.

Changes since V2:
- Added separate patches for renaming of functions and
  restructuring, adding new structures to support SD4/SD6 operations.
- Added proper suffixes to properties in dt binding.
- Removed unreachable code.
- Handled sdhci_cdns_uniphier_pltfm_data similar to sdhci_cdns_sd4_of_data
  as per the added structured design.
- Used dev_dbg instead of DEBUG_DRV in debug patch.

Changes since V1:
- Added separate patch for reformat/rename changes.
- Enabled MMC_SDHCI_IO_ACCESSORS in config MMC_SDHCI_CADENCE.
- Used proper properties in dt binding.
- Removed patch of config option to change default for sdhci timeout.
- Resolved issues reported by:
