The patch below fixes two problems for Kconfig on the BCM47xx platform:
- arch/mips/bcm47xx/gpio.c uses ssb_extif_* functions. Selecting
SSB_DRIVER_EXTIF makes sure those functions are available.
- arch/mips/pci/pci.c needs, when enabled, platform specific functions,
which are defined when SSB_PCICORE_HOSTMODE is enabled.
