VFIO: Add the SPR_DSA and SPR_IAX devices to the denylist
commit 95feb3160eef0caa6018e175a5560b816aee8e79 upstream.
Due to an erratum with the SPR_DSA and SPR_IAX devices, it is not secure to assign
these devices to virtual machines. Add the PCI IDs of these devices to the VFIO
denylist to ensure that this is handled appropriately by the VFIO subsystem.
The SPR_DSA and SPR_IAX devices are on-SOC devices for the Sapphire Rapids
(and related) family of products that perform data movement and compression.
