MIPS: Sibyte: Fix build for SIBYTE_BW_TRACE on BCM1x55 and BCM1x80.

  CC      arch/mips/mm/cerr-sb1.o
arch/mips/mm/cerr-sb1.c: In function ‘sb1_cache_error’:
arch/mips/mm/cerr-sb1.c:186:98: error: ‘M_BCM1480_SCD_TRACE_CFG_FREEZE’ undeclared (first use in this function)
arch/mips/mm/cerr-sb1.c:186:98: note: each undeclared identifier is reported only once for each function it appears in
make[1]: *** [arch/mips/mm/cerr-sb1.o] Error 1

This happens because 8deab114 [[MIPS]
Updated Sibyte headers] changed the headers but not all the users.
