ice: add basic devlink subfunctions support
Implement devlink port handlers responsible for ethernet type devlink
subfunctions. Create subfunction devlink port and setup all resources
needed for a subfunction netdev to operate. Configure new VSI for each
new subfunction, initialize and configure interrupts and Tx/Rx resources.
Set correct MAC filters and create new netdev.
For now, subfunction is limited to only one Tx/Rx queue pair.
Only allocate new subfunction VSI with devlink port new command.
Allocate and free subfunction MSIX interrupt vectors using new API
calls with pci_msix_alloc_irq_at and pci_msix_free_irq.
Support both automatic and manual subfunction numbers. If no subfunction
number is provided, use xa_alloc to pick a number automatically. This
will find the first free index and use that as the number. This reduces
burden on users in the simple case where a specific number is not
required. It may also be slightly faster to check that a number exists
since xarray lookup should be faster than a linear scan of the dyn_ports
xarray.
