samsung ExynosAuto SoC has two types of host controller interface to support the virtualization of UFS Device. One is the physical host(PH) that the same as conventaional UFSHCI, and the other is the virtual host(VH) that support data transfer function only. In this structure, the virtual host does not support like device management. This patch skips the interface configuration part that cannot be performed in the virtual host.
