FT: not a very clean way of managing the rescale of iqs in rx path, but this is done in
openair1/PHY/MODULATION/ul_7_5_kHz.c which doesn't have access to config parameters
to re-worked later.....
RX_IQRESCALELEN is setup in device libraries for all non expressmimo targets and acessed as an
external variable in ul_7_5_kHz.c. For expressmimo it is a macro (openair1/PHY/defs.h)
Regarding the value of this variable or macro: 18 is for 15 bits iqs, 15 is used for USRP, EXMIMO
