As reported by multiple people testing iwlwifi, device_release_driver()
can lead to a panic on secondary errors (usually during attach).
Disable device_release_driver() for the short-term to prevent the panic
but leave it in place so it can be re-worked and fixed properly for
the long-term more easily.

Add two new (though untested) functions to linux/device.h which are
dealing with manually managing the device/driver and are used by
at least one wireless driver. We may have to re-fine them in the
future.
Move the devres declarations further up so they can be used earlier
in the file.

This code implements a version of the devres framework found
working for various iwlwifi use cases and also providing functions
for ttm_page_alloc_dma.c from DRM.
Part of the framework replicates the consumed KPI, while others
are internal helper functions.
In addition the simple devm_k*malloc() consumers were implemented
and kvasprintf() was enhanced to also work for the devm_kasprintf()
case.
Addmittingly lkpi_devm_kmalloc_release() could be avoided but for
the overall understanding of the code and possible memory tracing
it may still be helpful.
Further devsres consumer are implemented for iwlwifi but will follow
later as the main reason for this change is to sort out overlap with
DRM.

Add backlight function to linuxkpi.
Graphics drivers expose the backlight of the panel directly so allow them to use the backlight subsystem so
user can use backlight(8) to configure them.

- Declare some static functions in linux_compat.c instead if inside
various header files.
- Prefix FreeBSD local functions in the LinuxKPI with "linux_" to
avoid symbol name conflicts in the future and to make debugging
easier.
- Make the "struct kobj_ktype" declaractions constant to shave off a
few bytes from the data segment.

- 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.
