mfd: vexpress: Export global functions to fix build error

Compiling vexpress client drivers as module results in error messages such as

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

This is because the global functions in drivers/mfd/vexpress-config.c are not
exported. Fix it.
