bnxt_en: Add a new phy_flags field to the main driver structure.

Copy the phy related feature flags from the firmware call HWRM_PORT_PHY_QCAPS to this new field. We can also remove the flags field in the bnxt_test_info structure. It's cleaner to have all PHY related flags in one location, directly copied from the firmware. To keep the BNXT_PHY_CFG_ABLE() macro logic the same, we need to make a slight adjustment to check that it is a PF.
