net: sfp: add support for a couple of copper multi-rate modules
Add support for the Fiberstore SFP-10G-T and Walsun HXSX-ATRC-1 modules. Internally, the PCB silkscreen has what seems to be a part number of WT_502. Fiberstore use v2.2 whereas Walsun use v2.6. These modules contain a Marvell AQrate AQR113C PHY, accessible through I2C 0x51 using the "rollball" protocol. In both cases, the PHY is programmed to use 10GBASE-R with pause-mode rate adaption. Unlike the other rollball modules, these only need a four second delay before we can talk to the PHY.
