[PATCH 04/12] mtd: move mtd_oob_mode_t to shared kernel/user space

[Brian Norris]

We will want to use the MTD_OOB_{PLACE,AUTO,RAW} modes in user-space
applications through the introduction of new ioctls, so we should make
this enum a shared type.

This enum is now anonymous and will be used in 8-bit fields (__u8 or
uint8_t).
