[3/5] octeontx2-af: Use the bitmap API to allocate bitmaps

Message ID 24177a9ee7043259448b735263d9cfd6a70e89a4.1669378798.git.christophe.jaillet@wanadoo.fr

  Use devm_bitmap_zalloc() instead of hand-writing it.

This also makes the comment "Allocate bitmap for 32 entry mcam" more
explicit because now 32 is really used in the allocation function, instead
of an obscure 'sizeof(long)'.
