ultrarisc_pcie_host_init() runs from the .init callback with the controller already enabled. Replace the capability search with dw_pcie_get_pcie_cap(). Since the lookup is performed lazily at the point of use, the driver no longer depends on any earlier caching step and the offset is always valid here.
