ice: manage profiles and field vectors
Implement functions to manage profiles and field vectors in hardware. In hardware, there are up to 256 profiles and each of these profiles can have 48 field vector words. Each field vector word is described by protocol id and offset in the packet. To add a new recipe all used profiles need to be searched. If the profile contains all required protocol ids and offsets from the recipe it can be used. The driver has to add this profile to recipe association to tell hardware that newly added recipe is going to be associated with this profile. The amount of used profiles depend on the package. To avoid searching across not used profile, max profile id value is calculated at init flow. The profile is considered as unused when all field vector words in the profile are invalid (protocol id 0xff and offset 0x1ff). Profiles are read from the package section ICE_SID_FLD_VEC_SW. Empty field vector words can be used for recipe results. Store all unused field vector words in prof_res_bm. It is a 256 elements array (max number of profiles) each element is a 48 bit bitmap (max number of field vector words). For now, support only non-tunnel profiles type.
