Subject: [PATCH v3 09/12] phy: exynos: Add platform device private data

Currently, the exynos PCIe PHY driver supports only single
phy ops making it unusable for other platforms. Add the phy_ops
as platform specific device data so as to extend this driver
to support all platforms using Samsung PHY.
