LinuxKPI: device: add a pr_debug("TODO") call to device_release_driver()

The logic in device_release_driver() got disabled in 93b14194acaf2
and since left alone. Add a pr_debug() call so we have a chance to
notice if that code is actually still in need to be fixed and re-enabled.

LinuxKPI: devres: divorce dem_kfree from lkpi_devm_kmalloc_release

dem_kfree() is called from all over the place and should actually
do something; contrary to lkpi_devm_kmalloc_release() it can also
take a const void *. We have to __DECONST() that though as the
entire devres framework does otherwise not take a const argument.

This was discovered during the rtw89 upadte to 6.16.

LinuxKPI: device.h add (*shutdown)

There are too many ways to call (*shutdown)() and others in Linux
it seems; rather than using the one from dev_pm_ops or directly
on the bus system device, some wireless drivers are setting it on
struct device_driver so add it.

Bump __FreeBSD_version as this changes the size of various other
structs which have struct device_driver embedded.

[How]
The function always returns false, like `pci_is_thunderbolt_attached()`
