firewire updates for v7.2

This update includes the following changes.

Unit drivers have been able to assign an arbitrary value in the mod_device
entry, which is typed as kernel_ulong_t. While storing the pointer value
is legitimate, conversion back to a pointer has been performed without
preserving const qualifier. Uwe Kleine-König introduced an union to
provide safer and more robust conversions, as part of the ongoing CHERI
enhancement work for ARM and RISC-V architectures. This update includes
changes in the sound subsystem, since the conversion pattern is widely
used in ALSA firewire stack.

The userspace applications can request the core function to perform
isochronous resource management procedures. Dingsoul reported
reference-count leak when these procedures are processed in workqueue
contexts. This update refactors the relevant code paths following a divide
and conquer approach. Consequently, it became clear that the issue still
remain only in the path when userspace applications delegate automatic
resource reallocation after bus resets to the core. In practice, the leak
is rarely triggered, and a complete fix is still in progress.
