[PATCH] cramfs: better MTD dependency expression

[Nicolas Pitre]

Commit b9f5fb1800d8 ("cramfs: fix MTD dependency") did what it says.
Since commit 9059a3493efe ("kconfig: fix relational operators for bool
and tristate symbols") it is possible to do it slightly better though.

Linus,

Viro once told me that my cramfs pull requests could go either to him or 
to you. I have only this one patch at the moment, and since it depends 
on a commit that recently appeared in your tree I'm therefore sending it 
directly to you.
