[PATCH 00/23] 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) a few minor cleanups
2) re-factor sdhci_start_signal_voltage()
3) fix not checking SDHCI_QUIRK2_NO_1_8_V when do voltage switch
4) fix get wrong data interrupt during no data transfer
5) fix unneeded retuning during card remove

Patch 17 added sdhci auto retune support (TUNING_MODE_3)
Many controller support hw auto retune, with it we do not
need do the frequent retuning after each runtime suspend/resume.

Patch 11~23 are imx esdhc driver clean up and fixes.
1) remove SDHCI_QUIRK_BROKEN_TIMEOUT_VAL
I also tried clean up all SDHCI_QUIRK_BROKEN_TIMEOUT_VAL in the tree,
seems a lot work that many controllers are affected, planned to do it later.
2) support setting tuning start point
This can make us bypass a few meaningless tuning commands at the start
3) add hw state restore function after system resume for low
power mode like LPSR on IMX7D which the controller state got lost.
Without it, the controller may not work after resume.
4) Patch 17~19 added hw auto retune support
5) fix strobe DLL lock wrong clock issue
This makes the eMMC HS400 mode strobe locks the correct clock rate
6) a few other reorgnization to make code more concentrate and maintainable
