Subject: [PATCH] dt-bindings: PCI: rockchip,rk3399-pcie: add missing maxItems to ep-gpios

Properties with GPIOs should define number of actual GPIOs, so add
missing maxItems to ep-gpios.  Otherwise multiple GPIOs could be
provided which is not a true hardware description.

Fixes: aa222f9311e1 ("dt-bindings: PCI: Convert Rockchip RK3399 PCIe to DT schema")
