baseband/turbo_sw: detect dependencies automatically

The meson for the turbo_sw PMD is updated to prevent the
requirement for any device specific toplevel flags to be
passed down (unlike what used to be the case with make).
The linking to the optional libraries is purely auto
detected at build time and flags are then set appropriately.
