Matt Redfearn 882164a4a9 ssb: Prevent build of PCI host features in module
Attempting to build ssb.ko with CONFIG_SSB_DRIVER_PCICORE=y results in
a build error due to use of symbols not exported from vmlinux:

ERROR: "pcibios_enable_device" [drivers/ssb/ssb.ko] undefined!
ERROR: "register_pci_controller" [drivers/ssb/ssb.ko] undefined!
make[1]: *** [scripts/Makefile.modpost:92: __modpost] Error 1

To prevent this, don't allow the host mode feature to be built if
CONFIG_SSB=m

Support for the Sonics Silicon Backplane bus.
You only need to enable this option, if you are
configuring a kernel for an embedded system with
this bus.
It will be auto-selected if needed in other
environments.
The module will be called ssb.

embedded devices to reduce the kernel size.
