common/sfc_efx/base: replace PCI efsys macros with functions

efsys macros that manipulate PCI devices cannot be defined in
common sfc_efx DPDK driver since in DPDK build the bus drivers
that provide required functionality are built after common drivers.

Replace the macros with function callbacks to remove that build
dependency. Drivers now should pass the callbacks directly to
efx function instead of defining implementation in efsys.
