PCI: dwc: ep: Expose integrated eDMA resources via EPC aux-resource API
Implement the EPC aux-resource API for DesignWare endpoint controllers
with integrated eDMA.
Currently, only report an interrupt-emulation doorbell register
(PCI_EPC_AUX_DOORBELL_MMIO), including its Linux IRQ and the write data
needed to trigger the interrupt.
If the DMA controller MMIO window is already exposed via a
platform-owned fixed BAR subregion, also provide the BAR number and
offset so EPF drivers can reuse it without reprogramming the BAR.
