dt-bindings: PCI: qcom-ep: Enable DMA for SM8450
Qualcomm SM8450 platform can (and should) be using DMA for the PCIe
Endpoint transfers.
Thus, extend the MMIO regions and interrupts in order to acommodate for
the DMA resources, mark iommus property as required for the platform.
Upstream devicetree doesn't provide support for the Endpoint mode of the
PCIe controller, so while this is an ABI break, it doesn't break any of
the supported platforms.
