[dpdk-dev] [PATCH v2 05/27] common/cnxk: support RoC API to free bandwidth profiles

[<skori@marvell.com>]

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

Implement RoC interface to free HW bandwidth profiles on
CN10K platform.

Signed-off-by: Sunil Kumar Kori <skori@marvell.com>

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