Drop device type; it's unneeded and unused.

Should technically be "fsl,mpc5200b-mdio", "fsl,mpc5200-mdio"; (I
know the lite5200b.dts doesn't have this either, but I'll write a
patch right now to fix it so that it's correct in .25)
I regret introducing "fsl,mpc5200b-*" at all since the 5200b is really
just a bug fix of the 5200 except for a very few incompatible device
changes. Just the nodes for specific incompatible devices need to
claim 5200b-<blah> in their compatible string (without claiming
5200-<blah>). It seems to me that specific silicon revision
differences by conventional is too fine grained for the compatible
field and if really needed can be discovered from the SVR.
I may even drop it in the .26 series. All device trees in the wild
claim compatibility with both so it won't break any existing boards.
heh; I guess that's just a long winded way to say make sure
fsl,mpc5200-mdio is in there so it remains possible to drop
mpc5200b-mdio in the future.

"mpc5200b-mscan", "mpc5200-mscan"; The '\0' is depreciated.

Drop device type

Same here; should include fsl,mpc5200-mdio
