[PATCH v3 0/4] Consolidate sdhci pltfm & OF drivers and get them self registered

[Shawn Guo <shawn.guo-QSEj5FYQhm4dnm+yROfE0A@public.gmane.org>]

Here are what the patch set does.

* Remove .probe and .remove hooks from sdhci-pltfm.c and make it be
  a pure common helper function providers.
* Add .probe and .remove hooks for sdhci pltfm drivers sdhci-cns3xxx,
  sdhci-dove, sdhci-tegra, and sdhci-esdhc-imx to make them self
  registered with calling helper functions created above.
* Migrate the use of sdhci_of_host and sdhci_of_data to
  sdhci_pltfm_host and sdhci_pltfm_data, so that OF version host and
  data structure works can be saved, and pltfm version works for both
  cases.
* Add OF common helper stuff into sdhci-pltfm.c, and make OF version
  sdhci drivers sdhci-of-esdhc and sdhci-of-hlwd become self
  registered as well, so that sdhci-of-core.c and sdhci-of.h can be
  removed.
* Eliminate include/linux/mmc/sdhci-pltfm.h with moving stuff into
  drivers/mmc/host/sdhci-pltfm.h.

And the benefits we gain from the changes are:

* Get the sdhci device driver follow the Linux trend that driver
  makes the registration by its own.
* sdhci-pltfm.c becomes simple and clean as it only has common helper
  stuff there now.
* All sdhci device specific things are going back its own driver.
* The dt and non-dt drivers are consolidated to use the same pair of
  .probe and .remove hooks.

Changes since v2:
* Drop imx mpc esdhc consolidation
* Fix checkpatch errors
* Add sdhci-of-core.c copyright into sdhci-pltfm.c

Changes since v1:
* Rebase on cjb's mmc-next tree
* Introduce helper function pair sdhci_pltfm_register and
  sdhci_pltfm_unregister
* Eliminate variable 'scratch' in .remove hook to make the code
  look simple
* Return ERR_PTR in sdhci_pltfm_init and use IS_ERR/PTR_ERR to check
  return value in .probe hooks
* Correct MODULE_AUTHOR statement
* Split esdhc conlidation patch to ease reviewing
