octeontx2-af: npc: Support for custom KPU profile from filesystem

Flashing updated firmware on deployed devices is cumbersome. Provide a
mechanism to load a custom KPU (Key Parse Unit) profile directly from
the filesystem at module load time.

When the rvu_af module is loaded with the kpu_profile parameter, the
specified profile is read from /lib/firmware/kpu and programmed into
the KPU registers. Add npc_kpu_profile_cam2 for the extended cam format
used by filesystem-loaded profiles and support ptype/ptype_mask in
npc_config_kpucam when profile->from_fs is set.

Usage:
  1. Copy the KPU profile file to /lib/firmware/kpu.
  2. Build OCTEONTX2_AF as a module.
  3. Load: insmod rvu_af.ko kpu_profile=<profile_name>
