[PATCH v2 7/8] dt-bindings: phy: uniphier-ahci: Add bindings for Pro4 SoC

[Kunihiko Hayashi <hayashi.kunihiko@xxxxxxxxxxxxx>]

Update AHCI-PHY binding document for UniPhier Pro4 SoC. Add a compatible
string, clock and reset lines for the SoC to the document.

Pro4 AHCI-PHY needs to control additional GIO clock line and reset lines
("pm", "tx", and "rx").
