net: mvpp2: Move probe function from MISC to ETH DM driver

Browse Source 
This patch moves the base_probe function mvpp2_base_probe() from the
MISC driver to the ETH driver. When integrated in the MISC driver,
probe is called too early before the U-Boot ethernet infrastructure
(especially the MDIO / PHY interface) has been initialized. Resulting
in errors in mdio_register().
