arch/sh/boards/mach-kfr2r09/setup.c: fix struct mtd_oob_ops build warning

arch/sh/boards/mach-kfr2r09/setup.c does not need to #include
<mtd/onenand.h>, and doing so causes a build warning, so drop that header
file.

In file included from ../arch/sh/boards/mach-kfr2r09/setup.c:28:
../include/linux/mtd/onenand.h:225:12: warning: 'struct mtd_oob_ops' declared inside parameter list will not be visible outside of this definition or declaration
     struct mtd_oob_ops *ops);
