USB2.0 PHY in Exynos5420 differs from Exynos5250 variant a bit, so use the
recently introduced dedicated compatible for Exynos5420.

The DTS change will wait till PHY driver adjustements get merged... or
if the difference is not critical, maybe using both compatibles (5420
and 5250) would have sense?

Best regards,

It won't work easily with both compatibles, because in the 5420 variant 
I've also changed the PHY indices (5420 has no device and second hsic 
phy). IMHO the dts change can wait for the next release.

Thanks, applied.
