This patch series add support for the Exynos USB 3.1 DRD combo phy, as found
in Exynos 9 SoCs like Google GS101. It supports USB SS, HS and DisplayPort,
but DisplayPort is out of scope for this series.

In terms of UTMI+, this is very similar to the existing Exynos850
support in this driver. The difference is that it supports both UTMI+
(HS) and PIPE3 (SS). Firstly, there are some preparatory patches to simplify
addition, while the bulk of the changes is around the SS part.
