Document ethernet PHY package nodes used to describe PHY shipped in bundle of 4-5 PHY. These particular PHY require specific PHY in the package for global onfiguration of the PHY package. Example are PHY package that have some regs only in one PHY of the package and will affect every other PHY in the package, for example related to PHY interface mode calibration or global PHY mode selection. The PHY package node should use the global-phys property and the global-phy-names to define PHY in the package required by the PHY driver for global configuration. It's also possible to specify the property phy-mode to specify that the PHY package sets a global PHY interface mode and every PHY of the package requires to have the same PHY interface mode.
