Making the entire mtd subsystem depend on HAS_IOMEM is a bit overkill.
HAS_IOMEM is only needed for real devices drivers.
nandsim and friends are perfectly usable on systems without IO memory.
I'm my case I'm using nandsim on UML to do some UBI and JFFS2 development.

Could you please work on this patch some more and make sure it does not
break s390 build (it does now).
Download the s390 cross-compiler from here:
http://kernel.org/pub/tools/crosstool/files/bin/
I used this one:
http://kernel.org/pub/tools/crosstool/files/bin/x86_64/4.6.0/x86_64-gcc-4.6.0-nolibc_s390x-linux.tar.bz2
I built the kernel with arch/s390/defconfig - it is out of date a bit,
but the kernel compiles with it.
Then I applied your patch and enabled all the available MTD options and
failed to build it. I've attached this .config file. Here is the command
line I used to build the kernel for s390x:
$ make ARCH=s390 CROSS_COMPILE=s390x-linux-
O=/home/dedekind/space/kernel-builds/l2-mtd-s390 -j16
The .config was put to /home/dedekind/space/kernel-builds/l2-mtd-s390,
obviously, and the path to the s390x-linux-* tools were in my PATH
environment variable.
There many errors, here is just one example:
make[4]: *** [drivers/mtd/lpddr/lpddr_cmds.o] Error 1
/home/dedekind/git/l2-mtd/include/linux/mtd/map.h:407:3: error: implicit declaration of function 'memcpy_fromio' [-Werror=implicit-function-declaration]
make[3]: *** [drivers/mtd/lpddr] Error 2
make[3]: *** Waiting for unfinished jobs....
Note, I tested your patch with todays l2-mtd tree on top of this commit:
705e4ee mtd: add leading underscore to all mtd functions
