If we allow to have board specific #ifdef inside mx6_common, I am afraid
we will get in ashort time the same mess we tried to order now.

What about moving the include in tqma6.h in a later point, I mean, after
CONFIG_SYS_TEXT_BASE is already set ?

mx6_common.h is already well protected and should not redefine something
if it is already set.
