precoding_stats timing is not part of ru->feptx_ofdm, but
ru->feptx_prec, so always print it.

Certain FH 7.2 use cases require 8 antennas, so make room to propagate
this down.

For the initialization of the xran library (split 7.2), we need some
parameters such as PRACH or frame config. However, to date,
initialization of split at level 7 use the split 8 openair0_config
structure, which does not have the necessary information.

Hence, add a single structure that contains that information.

* make a single call to various function
* make fill_rf_config() static, it is only used in this file
* do not initialize the number of antennas in openair0_cfg in
  init_NR_RU(), as it is already done in fill_rf_config()

Harmonize the call to openair0_transport_load(), by putting it in a
single place instead of multiple calls

Further, delay the call to ru_thread, for two reasons:

1) it is somewhat "symmetric" with local RF, which is done there as well

2) for the xran library, we need to read some parameters such as PRACH,
   frame format, etc. At the RU, the corresponding FAPI config request
   parameter structure is copied from the gNB to RU at the beginning of
   the ru_thread, so we have to wait for that to happen.

In order to speed up processing if precoding is disabled, we just copy
the pointer from txdataF to txdataF_BF, as opposed to do a full memcpy()
to duplicate the data. The same happens if we cannot have precoding,
i.e., in SISO.

Handle the case of precoding in allocation of the txdataF_BF structure
accordingly.
