[dpdk-dev] [PATCH 39/52] common/cnxk: add nix tm debug support and misc utils

[Nithin Dabilpuram <ndabilpuram@marvell.com>]

Add support to dump TM HW registers and hierarchy on error.
This patch also adds support for misc utils such as API to
query TM HW resource availability, resource pre-allocation
and static priority support on root node.
