The legacy user space for n900 relies on the MMC slot names.
Let's check if those are passed in pdata and use them.
Then when we have a generic MMC slot name binding we can
switch to use that assuming it works for the n900 legacy
user space too.
As this makes the DT booting compatible with legacy booting,
we should be able to start dropping omap3 legacy booting
support in v4.8.

Ulf, this is safe to pick separately to the MMC tree if it looks
acceptable to you.
