dt-bindings: PCI: qcom-ep: Describe optional dma-coherent property
Qualcomm SA8775P supports cache coherency on the PCIe Endpoint
controller.
Thus, allow "dma-coherent" property to be used for this device. This
fixes a part of the following error (the second part is fixed in the
next commit):
pcie-ep@1c10000: Unevaluated properties are not allowed ('dma-coherent', 'iommus' were unexpected)
Fixes: 4b220c6fa9f3 ("arm64: dts: qcom: sa8775p: Mark PCIe EP controller as cache coherent")
