staging: m57621-mmc: delete driver from the tree.
The license text in this driver is "interesting" and not really obvious that it is supposed to be able to be distributed in the kernel source tree. Yes, the MODULE_LICENSE() text says GPL, so it's probably ok, but to be safe, I am deleting this driver. I will be glad to add it back if the license is properly sorted out, but for now, this isn't worth the potential risk, I should have never taken it in the first place.

- ensure device-tree requirements are documented
