drivers: net: cpsw: fix get mdio base and gmii_sel reg from DT

Browse Source 
Since dra7x platforms address bus is define as 64 bits to support
LAPE, fdtdec_get_addr() returns a invalid address for mdio based
and gmii_sel register address. Fixing this by using
fdtdec_get_addr_size_auto_noparent() which will derive address
cell and size cell from its parent.
