UBI: kill CONFIG_MTD_UBI_BEB_RESERVE
CONFIG_MTD_UBI_BEB_RESERVE and MIN_RESEVED_PEBS are no longer used, since the amount of reserved eraseblocks for bad PEB handling is now derived from 'ubi->bad_peb_limit' (ubi's maximum expected bad eraseblocks).

- If the MTD device admits of bad eraseblocks (e.g. NAND flash), UBI
- reserves some amount of physical eraseblocks to handle new bad
- eraseblocks. When a physical eraseblock becomes bad, UBI uses these
- reserved physical eraseblocks to relocate the bad one. This
- configuration option specifies how many physical eraseblocks will be
- reserved for bad eraseblock handling (percents of total number of
- good physical eraseblocks on this MTD partition). If the underlying
- flash does not admit of bad eraseblocks (e.g. NOR flash), this value
- is ignored and nothing is reserved. Leave the default value if
- unsure.
