physmap/physmap_of contained compile-time check for mtd concatenation.
However thos modules did not consider that mtd concatenation can be
built as modules. Fix physmap/physmap_of to also support
CONFIG_MTD_CONCAT=m

Can we do something else to avoid these complex ifdefs? I'd vote for
making mtdconcat integral part of mtd core and just always have it
built-in - remove the Kconfig option and all the ifdefs all over the
place. Indeed, this is tiny piece of code, I believe this micro-modules
make little sense nowadays.

The same for mtdparts - but this is a different story.

Yes, I like this suggestion.

Dmitry, can you cook up such a patch? Otherwise I'll put it on my to-do 
list...

Yep.
