Merge branch 'pci/ctrl/exynos'

- Move samsung phy-exynos-pcie init all to exynos5433_pcie_phy_init()
  instead of splitting across phy_init() and phy_power_on() (Marek
  Szyprowski)

- Call phy_init() before phy_power_on() for samsung phy-exynos-pcie, as
  required by the PHY programming model (Marek Szyprowski)

* pci/ctrl/exynos:
  PCI: exynos: Correct generic PHY usage
  phy: samsung: phy-exynos-pcie: sanitize init/power_on callbacks
