Since this phy is shared by multiple devices including USB and PCIe, it is necessary to determine which device use this phy. This patch adds SoC-dependent functions to determine a device using this phy. When there is 'socionext,syscon' property in the pcie-phy node, the driver calls SoC-dependt function instead of checking .has_syscon in SoC-dependent data. The function configures the system controller to use phy for PCIe.
