Adjusting BaseBand drivers code to changes in FlexRAN 1.4.0:
- update usage of crc functions after API changes

Update the documentation describing Wireless Baseband Device:
- FlexRAN releases mapping table added
- download and build instructions for BBDEV turbo_sw driver in
  compliance with FlexRAN 1.4.0 release added
