ARM: 5938/1: ARM: L2: export outer_cache_fns

The 'outer_cache' variable is needed by the outer_inv_range(),
outer_clean_range() and outer_flush_range() functions, which are
declared as inline in asm/cacheflush.h.  Otherwise drivers built
as a loadable module, which access these functions, will have
an undefined symbol.
