Subject: [PATCH v2 0/8] arm64: dts: imx8: create common imx-pcie[0,1]-ep
 overlay file

Use common imx-pcie[0,1]-ep overlay file to enable PCIe EP function for
all imx8 boards.

unified pcie label name as below

imx8qm
pciea -> pcie0
pcieb -> pcie1

imx8qxp/imx8dxl
pcieb -> pcie0

imx8mp
pcie -> pcie0

other boards already use pcie0 and pcie1 naming. Orignal label still exist
to keep back compatiblity.
