mlxsw: core_acl_flex_keys: Add a bitmap to save which blocks are chosen

Browse source

Currently, mlxsw_afk_picker() chooses which blocks will be used for a
given list of elements, and fills the blocks during the searching - when a
key block is found with most hits, it adds it and removes the elements from
the count of hits. This should be changed as we want to be able to choose
which blocks will be placed in blocks 0 to 5.

To separate between choosing blocks and filling blocks, several pre-changes
are required. The indexes of the chosen blocks should be saved, so then
the relevant blocks will be filled at the end of search.

Allocate a bitmap for chosen blocks, when a block is found with most
hits, set the relevant bit in the bitmap. This bitmap will be used in a
following patch.
