6861781a80 phy: uniphier-pcie: Add SoC-dependent phy-mode function support
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.

04de8fa202 phy: uniphier-pcie: Add legacy SoC support for Pro5
Add legacy SoC support that needs to manage gio clock and reset and to skip
setting unimplemented phy parameters. This supports Pro5.

This specifies only 1 port use because Pro5 doesn't set it in the power-on
sequence.

9376fa634a phy: uniphier-usb3ss: Add Pro5 support
Pro5 SoC has same scheme of USB3 ss-phy as Pro4, so the data for Pro5 is
equivalent to Pro4.

f5fde094a7 phy: uniphier-pcie: Depend on HAS_IOMEM
The driver uses devm_ioremap_resource() which is only available when
CONFIG_HAS_IOMEM is set, so the driver depends on this option.
