This series fixes spotted issues with DW-MSHC support on Exynos4x12
SoCs and then enables DW-MSHC controller to handle eMMC memory on
Exynos4412-TRATS2 board. As opposed to using sdhci-s3c for eMMC,
MMC 4.4 extensions can be used and in general performance is improved.

Tested on Exynos4412-TRATS2 board.

The clock was missing CLK_SET_RATE_PARENT flag, which caused rate
setting failures due to inability of reconfiguration of second
divider behind it.

All SoCs from Exynos4x12 series contain the MSHC block, so its node can
be located in exynos4x12.dtsi. In addition, missing clock specifiers
are added, generic SoC attributes are moved from board dts files
to common dtsi file of SoC family and the node is renamed to a more
generic name to follow node naming recommendations.
