net: pch_gbe: Remove get_bus_info HAL abstraction
For some reason the pch_gbe driver contains a struct pch_gbe_functions with pointers used by a HAL abstraction layer, even though there is only one implementation of each function. This patch removes the get_bus_info abstraction. Its single implementation (pch_gbe_plat_get_bus_info) only sets values within a struct pch_gbe_bus_info which is never used, so we simply remove the call to it in pch_gbe_probe & remove struct pch_gbe_bus_info entirely. Now that struct pch_gbe_functions is empty we remove it entirely too. Signed-off-by: Paul Burton <paul.burton@mips.com> Signed-off-by: David S. Miller <davem@davemloft.net>
