PCI: dwc: ep: Implement capability search using PCI core APIs

The PCI core now provides generic PCI_FIND_NEXT_CAP() macros to search for
PCI capabilities, using config accessors we supply.

Use them in the DWC EP driver to implement dw_pcie_ep_find_capability()
instead of duplicating the algorithm.
