>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.
