Subject: [PATCH 11/20] phy: exynos5-usbdrd: Add to support for Exynos5433 SoC

From: Jaewon Kim <jaewon02.kim@...sung.com>

This patch adds driver data to support for Exynos5433 SoC.
The Exynos5433 has one USB3.0 Host and USB3.0 DRD(Dual Role Device).
Exynos5433 is simplar to Eyxnos7 but Exynos5433 have
one more USB3.0 Host controller.
