Add get_rate_matching() for rtl822x and rtl8251b, reading the serdes mode from phy. Change rtlgen_get_speed() so the register value is passed as argument. Using Clause 45 access, this value is retrieved differently. Driver instances are added for rtl8221b and rtl8251b for Clause 45 access only. The existing code is not touched, they use newly added functions. They also use the same rtl822x_config_init() and rtl822x_get_rate_matching() as these functions also can be used for direct Clause 45 access. Also Adds definition of MMC 31 registers, which cannot be used through C45-over-C22, only when phydev->is_c45 is set. Then 2 quirks are added for sfp modules known to have a rtl8221b behind RollBall, Clause 45 only, protocol.
