net/bnxt: add device configure operation

The dev_configure_op function calls bnxt_set_hwrm_link_config() to
setup the PHY.  This calls the new  bnxt_parse_eth_link_*() functions
to translate from the DPDK macro values to those used by HWRM calls,
then calls bnxt_hwrm_port_phy_cfg() to issue the HWRM call.

New HWRM calls:
bnxt_hwrm_port_phy_cfg:
	This command configures the PHY device for the port.
