For various revisions of a chipset if the signal pattern is changed for every revision, then the phy setting need to be updated correspondingly by measuring the signal. For getting correct signals the clock level and data de-emphasis levels needs to be adjusted. Since only these 2 values matter,we can move the same to dt, wherein we can have different dt files for every revision. This is an initial patchset towards achieving the same for exynos 5250 and can be later extended to future chipsets. V2: replaced moving of entire phy config structure with only required and justifiable conf registers. V3: Incorporated Mark Rutland's comments. V4: Rebased and included cros5250-common.dtsi.
