Yeah, caps reg is wired to 0, but it can do high speed.
Since we're VDD_330 only, I'm not sure the driver type flags do
anything, but I'm still good with having consistency.

Interested in porting over the DMA support? :)
I also noticed that the emmc wrapper module claims it can run with a
clock from 50-100mhz, and the arasan says it can run at up to 50, 52, or
208mhz depending on SD/MMC mode. Could we get a boost from running the
module at a higher clock rate?
