[PATCH 17/31] common/cnxk: expose different params for bp config

[Nithin Dabilpuram]

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

Currently same bp percentage is applied on SPB and
LPB pool but both pools can be configured with different
bp level.

Added one more parameter so that separate threshold parameters
can be passed for SPB and LPB pools.
