This patchset fixes the issues reported by Heiner [0] with the odroid-c2.
In a nutshell, this series does the following:

* Make sure the mmc clock rate is not set higher than what is requested
* Reset the tuning values on mmc power cycle instead of POWER_ON
* Add tuning of the tx phase to the tuning function.

This fixes the problem seen on the odroid-c2, both for hs200 and hs400.
To check for regression, this series has also been tested on the gxl

Ulf, could you please pick this as fixes for v4.14 ?
