[dpdk-dev] [PATCH 6/7] net/bnxt: fix some link related issues

This patch fixes some link related issues that can occur because:
bnxt_hwrm_port_phy_cfg() was setting enables inappropriately.
bnxt_hwrm_port_phy_qcfg() was overly complex.
bnxt_get_hwrm_link_config() was basing the speed on the link status.
bnxt_get_hwrm_link_config() was using the incorrect macros for auto_mode
we are not using supported speeds from phy_qcfg for auto mask.
Fixes: 7bc8e9a227cc ("net/bnxt: support async link notification")
