[PATCH V2 00/15] a few sdhci/imx clean up and fix patches

[Dong Aisheng]

Patch 1~10 are mainly sdhci cleanup patches while patch 7,9,10
are fixes which seems needed for stable tree as well.

The main work is:
1) using more robust mmc_regulator_set_vqmmc 
2) add auto retune support
3) improve sdhci-esdhc-imx stability
4) add state save and restore for low power mode

Change Log:
v1->v2:
 * address all Andrian's comments
 * below patches are dropped
  mmc: sdhci: move sdhci_get_cd() forward to avoid declaration
  mmc: core: fix a comment typo
  mmc: sdhci: re-factor sdhci_start_signal_voltage()
  mmc: core: mmc_regulator_set_vqmmc not return error if vqmmc/vmmc not
    exist
  mmc: sdhci: check SDHCI_QUIRK2_NO_1_8_V when do voltage switch
  mmc: sdhci: rename quirk SDHCI_QUIRK_MULTIBLOCK_READ_ACMD12
	Above clean up is not needed so far according to Andrian.

  mmc: sdhci: fix incorrect get data interrupt during no data transfer
	This one is not needed anymore cause Andrian had another fix
	already in tree.
	(commit 0e0a35d2d4058 mmc: sdhci: Track whether a reset is pending)

  mmc: core: disable auto retune during card detection process
	This one will sent out in another patch series to fix in CORE.
