phy: uniphier-pcie: Add SoC-dependent phy-mode function support

Browse Source 
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.
