when testing on haswell, using apt-get to install LimeSDR
libraries and includes, it put it in /usr/include, not
/usr/local/include

Beamforming is now only done when necessary. This patch is based on one from enhancement-10-harmony.

reduced the max number of antenna ports to 6 to save memory (we are not using antenna port >5 anyway)
mult_cpx_conj_vector can now also do multiply add
beam_precoding now uses mult_cpx_conj_vector

I am not sure this is the correct solution.

The problem seems to be that the RRH GW does not use ITTI
and thus the type 'as_nas_info_t' is not defined, and then
the compilation fails.

The simple fix is to include 'as_message.h' in
'openair2/RRC/LITE/defs.h' if ENABLE_ITTI is not
defined. Maybe it's not good. RRH GW compiles with this fix.

"frame" is not defined, we pass 0 instead.

Maybe not the right solution.
