rGfd27f86dd71b: LinuxKPI: switch jiffies and timer->expire to unsigned long

Summary

It seems these function in Linux work with unsigned long and not int.
Start simply replacing the int where I came across it while debugging
a wireless driver timer modification. Also sprinkle in some "const".

72	Linux removed timespec_to_jiffies as of 2019, we can follow suit after checking that there are no users left (also jiffies_to_timespec)

sys/compat/linuxkpi/common/include/linux/jiffies.h
72	I see no jiffies_to_timespec I also see no timespec_to_jiffies in drm-kmod 5.4-lts, 5.10-lts, 5.15-lts, and 6.1-lts. I seem another #define in sys/dev/drm2/drm_os_freebsd.h which likely is also unused then and should probably just go as well? I'll put another review up for both and add Phabgroup(x11) to catch the graphics people better.
