dt-bindings: PCI: fsl,imx6q-pcie-ep: Add compatible string fsl,imx8q-pcie-ep

Add new compatible string fsl,imx8q-pcie-ep for iMX8Q.

The 'reg-names' property only needs 'dbi' and 'addr_space' because the
others are located at a default offset. The new 'clock-names' property
aligns with the Root Complex (RC) naming.
