The newly introduced vexpress mfd driver in linux-3.8-rc
provides access to configuration functions, but the
interfaces are not exported to modules, which breaks
when the vexpress regulator driver tries to use them.

Without this patch, building allmodconfig results in:

ERROR: "__vexpress_config_func_get" [drivers/regulator/vexpress.ko] undefined!
ERROR: "vexpress_config_func_put" [drivers/regulator/vexpress.ko] undefined!
