Qualcomm SA8775P supports cache coherency on the PCIe EP controller.
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")
