Add mlx5 live migration driver and v2 migration protocol
This series adds mlx5 live migration driver for VFs that are migration capable and includes the v2 migration protocol definition and mlx5 implementation.
The mlx5 driver uses the vfio_pci_core split to create a specific VFIO PCI driver that matches the mlx5 virtual functions. The driver provides the same experience as normal vfio-pci with the addition of migration support.
In HW the migration is controlled by the PF function, using its mlx5_core driver, and the VFIO PCI VF driver co-ordinates with the PF to execute the migration actions.
The bulk of the v2 migration protocol is semantically the same v1, however it has been recast into a FSM for the device_state and the actual syscall interface uses normal ioctl(), read() and write() instead of building a syscall interface using the region.
Several bits of infrastructure work are included here: - pci_iov_vf_id() to help drivers like mlx5 figure out the VF index from a BDF - pci_iov_get_pf_drvdata() to clarify the tricky locking protocol when a VF reaches into its PF's driver - mlx5_core uses the normal SRIOV lifecycle and disables SRIOV before driver remove, to be compatible with pci_iov_get_pf_drvdata() - Lifting VFIO_DEVICE_FEATURE into core VFIO code
This series comes after alot of discussion. Some major points: - v1 ABI compatible migration defined using the same FSM approach: https://lore.kernel.org/all/0-v1-a4f7cab64938+3f-vfio_mig_states_jgg@nvidia.com/ - Attempts to clarify how the v1 API works: Alex's: https://lore.kernel.org/kvm/163909282574.728533.7460416142511440919.stgit@omen/ Jason's: https://lore.kernel.org/all/0-v3-184b374ad0a8+24c-vfio_mig_doc_jgg@nvidia.com/ - Etherpad exploring the scope and questions of general VFIO migration: https://lore.kernel.org/kvm/87mtm2loml.fsf@redhat.com/
NOTE: As this series touched mlx5_core parts we need to send this in a pull request format to VFIO to avoid conflicts.

vfio/mlx5: Implement vfio_pci driver for mlx5 devices
This patch adds support for vfio_pci driver for mlx5 devices.
It uses vfio_pci_core to register to the VFIO subsystem and then implements the mlx5 specific logic in the migration area.
The migration implementation follows the definition from uapi/vfio.h and uses the mlx5 VF->PF command channel to achieve it.
This patch implements the suspend/resume flows.

vfio/pci: Introduce vfio_pci_core.ko
Now that vfio_pci has been split into two source modules, one focusing on the "struct pci_driver" (vfio_pci.c) and a toolbox library of code (vfio_pci_core.c), complete the split and move them into two different kernel modules.
As before vfio_pci.ko continues to present the same interface under sysfs and this change will have no functional impact.
Splitting into another module and adding exports allows creating new HW specific VFIO PCI drivers that can implement device specific functionality, such as VFIO migration interfaces or specialized device requirements.

vfio/pci: Split the pci_driver code out of vfio_pci_core.c
Split the vfio_pci driver into two logical parts, the 'struct pci_driver' (vfio_pci.c) which implements "Generic VFIO support for any PCI device" and a library of code (vfio_pci_core.c) that helps implementing a struct vfio_device on top of a PCI device.
vfio_pci.ko continues to present the same interface under sysfs and this change should have no functional impact.
Following patches will turn vfio_pci and vfio_pci_core into a separate module.
This is a preparation for allowing another module to provide the pci_driver and allow that module to customize how VFIO is setup, inject its own operations, and easily extend vendor specific functionality.
At this point the vfio_pci_core still contains a lot of vfio_pci functionality mixed into it. Following patches will move more of the large scale items out, but another cleanup series will be needed to get everything.
