ioremap balanced with iounmap for drivers/mtd subsystem
ioremap must be balanced by an iounmap and failing to do so can result
in a memory leak.
Tested (compilation only) with:
- allmodconfig
- Modifying drivers/mtd/maps/Kconfig and drivers/mtd/nand/Kconfig to
make sure that the changed file is compiling without warning
