From: Piotr Raczynski <piotr.raczyn...@intel.com>
Make devlink allocation function generic to use it for PF and for SF.
Add function for SF devlink port creation. It will be used in next
patch.

Why do we need priv_size and ops if those are not used in the function?
Shouldn't it be line:
devlink = devlink_alloc(&ice_devlink_ops, sizeof(struct ice_pf), dev);
in ice_devlink_alloc changed to take the passed param?
