Currently, the documentation only contains instructions for enabling
SRIOV support for VFIO compiled as a module, but doesn't have any
instructions on how to do the same for cases where VFIO is built-in.
Add these instructions.

Wrong headline case:
"doc: clarify vfio doc for built-in modules": vfio --> VFIO
Invalid patch(es) found - checked 1 patch
