net/macb: Add arch specific routine to get mdio control

Browse source 
SPEAr310 and SPEAr320 Ethernet interfaces share same MDIO lines to control their
respective phys. Currently there is a fixed configuration in which only a
particular MAC can use the MDIO lines.

Call an arch specific function to take control of specific mdio lines at
runtime.
