[U-Boot] [PATCH] cmd: mdio/mii: add Kconfig help and allow break dependency

[Ramon Fried]

* Add Kconfig help describing the purpose of each command.
* Add CONFIG_CMD_MDIO so it could be selected individually, as
  it doesn't depend on the mii command.
* Add Kconfig imply to mii to automatically select the mdio
  command.
