[MIPS] TX49: Fix use of CDEX build_store_reg()
The commit a923660d786a53e78834b19062f7af2535f7f8ad accidently prevents TX49 from using CDEX. Use build_dst_pref() only if prefetch for store was really available. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
