dt-bindings: imx6q-pcie: Handle various clock configurations
The i.MX SoCs have various clock configurations routed into the PCIe IP,
the list of clock is below. Document all those configurations in the DT
binding document.
All SoCs: pcie, pcie_bus
6QDL, 7D: + pcie_phy
6SX: + pcie_phy pcie_inbound_axi
8MQ: + pcie_phy pcie_aux
8MM, 8MP: + pcie_aux
