net/phy: support the mv88e6352 switch
This patch add support for the configuration of an external switch from the 88E6xxx series from Marvell trough an MDIO link using indirect adressing. This can be used if we do not want to use an EEPROM for the configuration. This driver is not generic and was not tested on other switches than the 88e6352. This is proposed as a first implementation that is somewhat limited but works and that can be used as a basis for further developments for this switch family.
