octeontx2-af: NPC MCAM entry alloc/free support
This patch adds NPC MCAM entry management and support for
allocating and freeing them via mailbox. Both contiguous and
non-contiguous allocations are supported. Incase of contiguous,
if request cannot be met then max contiguous number of available
entries are allocated.
High or low priority index allocation w.r.t a reference MCAM index
is also supported.
