Subject: [PATCH v4 net-next 4/9] bnxt_en: Use ignore_ari devlink parameter

This patch adds support for ignore_ari generic permanent mode
devlink parameter. This parameter is disabled by default. It can be
enabled using devlink param commands.

ignore_ari - If enabled, device ignores ARI(Alternate Routing ID)
capability, even when platforms has the support and creates same number
of partitions when platform does not support ARI capability.
