net: dsa: felix: build as module when tc-taprio is module

felix_vsc9959.c calls taprio_offload_get() and taprio_offload_free(),
symbols exported by net/sched/sch_taprio.c. As such, we must disallow
building the Felix driver as built-in when the symbol exported by
tc-taprio isn't present in the kernel image.

Fixes: 1c9017e44af2 ("net: dsa: felix: keep reference on entire tc-taprio config")
