[dpdk-stable] [PATCH 19.11 1/2] net/bnxt: support speed capabilities query

[Kalesh A P <kalesh-anakkur.purayil@broadcom.com>]

From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>

[ upstream commit 85cf7f2bba0f665fe91710cd1cf0ca852f73890a ]

Added information about supported speeds for the port in the
"dev_infos_get". As other PMDs are returning the speed capabilities,
apps may expect this behavior from bnxt PMD.
