[PATCH v5 07/16] PCI: dwc: eswin: Use cached PCIe capability offset

[Hans Zhang]

eswin_pcie_link_up() is the .link_up callback, so it is called on every
link state poll. Replace the dw_pcie_find_capability() call with
dw_pcie_get_pcie_cap() so that the capability list is walked only once,
and store the offset in a u8 as everywhere else.
