bus/pci: remove Mellanox kernel driver type

This reverts commit 0cb86518db57d35e0abc14d6703fad561a0310e2.

The PCI bus now reports DC when faced with a device bound to an unknown
driver and, in such a case, the IOVA mode is selected against physical
address availability.

As a consequence, there is no reason for this special case for Mellanox
drivers.

Fixes: 703458e19c16 ("bus/pci: consider only usable devices for IOVA mode")
