lantiq: ltq-tapi: fix compilation with newer Linux kernels

Compiling the ltq-tapi driver against Linux 5.4 results in a compile
error complaining that the size of struct sched_param is not known.
Switch the existing "sched/types.h" include to reference
include/uapi/linux/sched/types.h to fix compilation against Linux 5.4.
