dt-bindings: pci: add PHY properties to Armada 7K/8K controller bindings
Armada CP110 PCIe controller can have from one to four PHYs for configuring SERDES lanes (PCIe x1, PCIe x2 or PCIe x4). Describe the phys and phy-names properties in the bindings. Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
