Import patch "net: phy: realtek: mark existing MMDs as present"
When using Clause-45 mode to access RealTek RTL8221B 2.5G PHYs some
versions of the PHY fail to report the MMDs present on the PHY.
Mark MMDs PMAPMD, PCS and AN which are always existing according to
the datasheet as present to fix that.
