Is it still valid or was it just copied from old code?

So when I did the bring-up of this controller, for some reason I thought
this was needed. But I guess that's not the case since I get this
without it:

[    5.168918] mmc0: new ultra high speed SDR104 SDHC card at address

So will drop in the next version.

Keep in mind that I have no way to test the sdhc_4, so I'll drop it from
there as well.
