fix PCI resouce allocation for SSB PCI host bridge

fix PCI resouce allocation for SSB PCI host bridge

The defined offset is wrong and the fixup-code overrides it
later on so that it never gets used for most PCI devices.
Unfortunately the yenta-socket allocates its own resources
and crashes because of the wrong mem_offset.

It seems that the offset and fixup code came from 2.4 where
resource allocation was handled differently.

This patch removes the unneeded parts and thus enables
the yenta_socket on the WRT54G3G platform.

It was tested on Asus WL500G-Premium (v1 and v2), Linksys
WRT54G3G, Netgear WGT634U
