The vfio/pds series for locking updates/fixes in the following link
made some changes that can also be done for other vendor's vfio
drivers. Specifically, changing the reset lock from a spinlock to mutex
and also calling mutex_destroy() in the vfio device release callback.

https://lore.kernel.org/kvm/20231122192532.25791-1-brett.creeley@amd.com/

So, this series makes these changes in order to remain separate from
the vfio/pds series linked above.

Note, that I don't have the required hardware to test on this vendor's
hardware, so help would be appreciated.
