[PATCH v3 2/6] PCI: dwc: ep: Move dw_pcie_ep_find_ext_capability()

[Niklas Cassel <cassel@kernel.org>]

Move dw_pcie_ep_find_ext_capability() so that it is located next to
dw_pcie_ep_find_capability().

Additionally, a follow-up commit requires this to be defined earlier
in order to avoid a forward declaration.
