lantiq: ltq-tapi: add kernel 5.10 compatiblity
Due to SCHED_FIFO being a broken scheduler model, all users of
sched_setscheduler() are converted to sched_set_fifo_low() upstream and
sched_setscheduler() is no longer exported.
The callback handling of the tasklet API was redesigned and the macros
using the old syntax renamed to _OLD.
