Thanks for the review!

At the moment I'm _not_ convinced that there's a good reason to
specify 8 banks.  We appear to have lied and said 1 bank on
exynos5250-snow (ARM Chromebook) and I don't know of any bad side
effects.

The code I'm looking at right now indicates 8 banks.  We need to track
down why someone did that but it doesn't seem totally crazy to allow
specifying the proper number of banks so I figured I'd send this patch
up.

If you prefer, we can leave this patch hanging until we actually track
down if specifying 8 banks was really needed.
