octeontx2-af: npc: cn20k: add subbank search order control

Browse source

CN20K NPC MCAM is split into 32 subbanks that are searched in a
predefined order during allocation. Lower-numbered subbanks have
higher priority than higher-numbered ones.

Add a runtime "srch_order" to control the order in which
subbanks are searched during MCAM allocation.
