[2.6 patch] select for drivers/mtd

[Adrian Bunk <bunk@stusta.de>]

The patch below switches options to use select where appropriate.

One of the dependencies of MTD_GEN_PROBE was on MTD_INTELPROBE that
isn't in Linus' tree. If this symbol is present in the mtd cvs, a
similar select is needed there.

What's the purpose of the MTD_DOCECC option, which has always the same 
value as the MTD_DOCPROBE option?
