[dpdk-dev] [PATCH v2 11/27] common/cnxk: support RoC API to get stats to index

[<skori@marvell.com>]

From: Sunil Kumar Kori <skori@marvell.com>

CN10K platform supports different stats for HW bandwidth profiles.
Implement RoC API to get index for given stats type.

v2:
 - Rebase support on latest DPDK
 - Handled multilevel chaining for linear hierarchy
 - Review comments incorporated
