When CONFIG_SYS_FSL_QORIQ_CHASSIS2 is not defined, QMAN frequency will not
be initialized, and QMAN will have a wrong frequency display.

Can we just move the original copy of the above lines out of the #ifdef? I
don't see any reason to do it the same way in two places.

You mean delete #ifdef? It will have a compiling error, won't it? See
include/e500.h, the freqQMAN is withing #ifdef.
