qcacmn: Add >=4.15 kernel support to qdf_timer

Browse source 
The various setup_*_timer() APIs were removed from the linux kernel in
4.15, and replaced with similar timer_setup_*() APIs. Add conditional
compilation to qdf_timer to use the correct APIs depending on the
version of the kernel being compiled against.
