ice: add ice_adapter for shared data across PFs on the same NIC
There is a need for synchronization between ice PFs on the same physical
adapter.
Add a "struct ice_adapter" for holding data shared between PFs of the
same multifunction PCI device. The struct is refcounted - each ice_pf
holds a reference to it.
Its first use will be for PTP. I expect it will be useful also to
improve the ugliness that is ice_prot_id_tbl.
