[PATCH 2/7] ARM: samsung: Change __s5p_mipi_phy_control() function signature

[Sylwester Nawrocki]

Replace pdev argument __s5p_mipi_phy_control() helper with plain int
so MIPI-CSIS hardware instance index can be passed directly making
the function usable on platforms instantiated from device tree.
