net: sfp: add some quirks for GPON modules 



[ Upstream commit b0eae33b2583dceb36224619f9fd85e6140ae594 ]

Marc Micalizzi reports that Huawei MA5671A and Alcatel/Lucent G-010S-P
modules are capable of 2500base-X, but incorrectly report their
capabilities in the EEPROM.  It seems rather common that GPON modules
mis-report.

Let's fix these modules by adding some quirks.
