cc2723370b LinuxKPI: add fsleep()
Add fsleep() function now required by rtw88.  This seems to be
making a decision depending on time to sleep on how to sleep.
Given our compat framework already is lenient on how long to sleep,
this is a cut down version.

05f56ac92f LinuxKPI: Force the usleep_range() function to sleep instead of spinning on the timer.
This allows other threads to execute, typically during hardware waiting loops.
This also maches how the function works in Linux.

7cf1c51588 Implement msleep_interruptible() in the LinuxKPI. While at it use pause_sbt()
instead of pause() in the msleep() function to avoid rounding errors when
converting delay values forth and back. Add a guard for a delay value
of zero milliseconds which is undefined.

8d59ecb214 Finish process of moving the LinuxKPI module into the default kernel build.
- Move all files related to the LinuxKPI into sys/compat/linuxkpi and
  its subfolders.
- Update sys/conf/files and some Makefiles to use new file locations.
- Added description of COMPAT_LINUXKPI to sys/conf/NOTES which in turn
  adds the LinuxKPI to all LINT builds.
- The LinuxKPI can be added to the kernel by setting the
  COMPAT_LINUXKPI option. The OFED kernel option no longer builds the
  LinuxKPI into the kernel. This was done to keep the build rules for
  the LinuxKPI in sys/conf/files simple.
- Extend the LinuxKPI module to include support for USB by moving the
  Linux USB compat from usb.ko to linuxkpi.ko.
- Bump the FreeBSD_version.
- A universe kernel build has been done.
