[PATCH] drop CONFIG_PARTITION_NEED_MTD

[PATCH] drop CONFIG_PARTITION_NEED_MTD

[Sascha Hauer]

With CONFIG_PARTITION_NEED_MTD enabled we use mtd rather than devfs
directly to create partitions on mtd devices. Since:

|
|     mtd: nand: bb: use mtd api directly
|
|     The devfs layer just adds an addition indirection between mtd
|     and the bb devices with no purpose. Drop it.

The bad block aware device creation doesn't work if this option
is disabled. With this we remove CONFIG_PARTITION_NEED_MTD and always
use mtd partitions on mtd devices.
