net: sfp-bus: allow SFP quirks to override Autoneg and pause bits
Allow SFP quirks to override the Autoneg, Pause and Asym_Pause bits in
the support mask.
Some modules have an inaccessible PHY on which is only accessible via
2500base-X without Autonegotiation. We therefore want to be able to
clear the Autoneg bit. Rearrange sfp_parse_support() to allow a SFP
modes quirk to override this bit.
