From: Kalesh AP <kalesh-anakkur.purayil at broadcom.com>
The "active_fec_signal_mode" in HWRM_PORT_PHY_QCFG response
does not return correct value till the link is up. Driver cannot
rely on active_fec_signal_mode while setting autoneg speed.
While setting autoneg speed, driver is currently checking only
"auto_link_speed_mask". Fixed to check "auto_pam4_link_speed_mask"
as well. Also, while setting auto mode and setting speed mask,
driver will have to set both NRZ and PAM4 mask.
Fixes: c23f9ded0391 ("net/bnxt: support 200G PAM4 link")
