a few sdhci/imx clean up and fix patches

Quoted 2 lines · 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.

I have ack'ed all the sdhci-related patches. i.e. all but patch 7 the dt bindings change.

I am not sure what needs to be done for stable. I would suggest these patches are queued for 4.8, then Dong can send the relevant patches to the linux-stable mailing list separately after -rc1.

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 Adrian'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 Adrian.

mmc: sdhci: fix incorrect get data interrupt during no data transfer
This one is not needed anymore cause Adrian 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.
