nfp: add support for per-PCI PF mailbox
When working with devlink-related functionality for locking reasons
it's easier to create a new mailbox per-PCI PF device than try to
use one of the netdev/vNIC mailboxes.
Define new mailbox structure and resolve its symbol during probe.
For forward compatibility allow silent truncation of mailbox command
data.
