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. Signed-off-by: Mathias Kresin <dev@kresin.me> ltq tapi
