Add device tree binding documentation for the Endpoint in PCIe Designware driver. Signed-off-by: Gustavo Pimentel <gustavo.pimentel@synopsys.com> --- Change v1->v2: - Add a missing log description. - Add "snps,dw-pcie" compatible string following Kishon's suggestion. Change v2->v3: - Reverted pcie_ep name to pcie. Changes v3->v4: - Reverted "snps,dw-pcie-rc" compatible string requested by Rob Herring.
