[PATCH 1/3] target.mk: silence CPU_TYPE doesn't correspond to a known type

[Petr Štetiar]

Following command:

 $ ./scripts/dump-target-info.pl targets

currently generates bunch of following warnings:

 include/target.mk:269: CPU_TYPE "cortex-a15" doesn't correspond to a known type

just because there is no CPU_CFLAGS_cortexa-15 defined for that CPU and
there is no value in this warning, so lets acknowledge such CPU_TYPEs
and do not print those warnings.
