stmmac: fix phy naming inconsistency

[Alessandro Rubini]

After commit "db8857b stmmac: use an unique MDIO bus name" my
device stopped being probed because two different names were being
used in different places. This fixes the inconsistency.

Before the commit, the phy was identified like this and stuff worked:

     PHY ID 20005c90 at 1 IRQ 0 (506:01) active

After that commit, I get 

     PHY ID 20005c90 at 1 IRQ 0 (STMMAC MII Bus-1:01) active
     PHY stmmac-1:01 not found

In one place, "stmmac" is a static string, on the other the commit
used the name field of the bus that was "STMMAC MII Bus", so I changed
this older string to be nicer -- without spaces.

Maybe the name is available where "stmmac" is spelled out, but I
didn't check.

Now it works for me:

    eth1: PHY ID 20005c90 at 1 IRQ 0 (stmmac-1:01) active
    PHY: stmmac-1:01 - Link is Up - 100/Full
