[PATCH] ssb: Fix extif compile error

[PATCH] ssb: Fix extif compile error

[Michael Buesch]

This is a compilation fix for a recently applied patch
[PATCH 2/3] Use SSB EXTIF in SSB MIPS core driver
when the extif core is not enabled.

This also makes the extif driver depend on CONFIG_SSB_DRIVER_EXTIF
(sorry, my mistake).
