Fixes and improvements for SDHCI on Armada 38x

Hi,

this series brings fixes and improvements for the SDHCI controller of the Armada 38x SoCs.

The changes for this forth version was done on the 1st and 4th patches, see the changelog for the details.

The first two patches are fixes and should be also applied on the stable branch (I added stable in copy for this).

The first one removes the SDR50 and DDR50 mode timing from the capabilities of the controller because the current implementation doesn't support it.

The second one fix controller's caps according to the limitation of the hardware.

The third one extends the Device Tree binding of the Armada 38x. It allows using the SDIO3 configuration register.

The forth patch adds the support of this new register in the driver. Thanks to this one, specific clock adjustments can be done in order to support the SDR50 and DDR50 modes timing.

The fifth patch is device tree clean-up.

The sixth patch update the SDHCI node on Armada 38x in order to use the new register and then to be able to support the SDR50 and DDR50 modes timing.

Finally, the seventh patch add the description of SDHCI for the Armada 388 RD board which was missing.

Patches 1 to 4 should be merged through the mmc tree and patches 5 to 7 should be merged through mvebu and then arm-soc.

Patch 4 depend on patch 2.
Patch 2 depend on patch 1.
And patch 1 depend on commit aa8165f91442 "mmc: sdhci-pxav3: do the mbus window configuration after enabling clocks" which have been merged.

But as all this patch should be merged through the same tree it would not be a problem

The patches 5 to 7 depend on the patches already merged in mvebu.

As they are fixes, patches 1 and 2 should be merged in 3.18-rc or at least in 3.19 and then they will be part of 3.18.1. For the other patches it would be nice if they could be part of 3.19.

Thanks,

Gregory
