Arnd , there is an existing api _of_phy_get that gets a phy by index. 
However it is not exported and is called from of_phy_get which is in 
turn called from devm_of_phy_get.

My plan is to create a new function maybe devm_of_phy_get_by_index that 
calls _of_phy_get directly? What are your thoughts?
