ice: Add switch recipe reusing feature
New E810 firmware supports the corresponding functionality, so the driver
allows PFs to subscribe the same switch recipes. Then when the PF is done
with a switch recipes, the PF can ask firmware to free that switch recipe.
When users configure a rule to PFn into E810 switch component, if there is
no existing recipe matching this rule's pattern, the driver will request
firmware to allocate and return a new recipe resource for the rule by
calling ice_add_sw_recipe() and ice_alloc_recipe(). If there is an existing
recipe matching this rule's pattern with different key value, or this is a
same second rule to PFm into switch component, the driver checks out this
recipe by calling ice_find_recp(), the driver will tell firmware to share
using this same recipe resource by calling ice_subscribable_recp_shared()
and ice_subscribe_recipe().
When firmware detects that all subscribing PFs have freed the switch
recipe, firmware will free the switch recipe so that it can be reused.
This feature also fixes a problem where all switch recipes would eventually
be exhausted because switch recipes could not be freed, as freeing a shared
recipe could potentially break other PFs that were using it.
