mtd: Add parameter to allow erasing bad blocks
While erasing bad blocks is a potentially dangerous operation
it is sometimes needed during development or when some foreign
code has touched the flash.
This patch adds a device parameter 'erasebad' to allow erasing
bad blocks. Since this is not wanted during production this is
behind a Kconfig option.
