Supporting the UFS turbo-write mode

I'm not sure that Linux has a filesystem suitable for MLC or QLC flash.
As I understand it ubifs has given up supporting MLC and one presumes QLC would have even more problems.

This patch causes ubifs to refuse to handle MLC flash rather than allow people to build systems that would be unreliable (i.e. using UBIFS on top of MLC).

This mailing list item talks about ubihealthd (never merged into mtd-utils) which was a proposal for handling less reliable NAND.

Happy to be updated/proven wrong :-)
