[PATCH v3 13/13] mtd: decommission the NAND museum

Upstream linux commit f7025a43a9da26.

The MTD subsystem has its own small museum of ancient NANDs in a form of
the CONFIG_MTD_NAND_MUSEUM_IDS configuration option. The museum contains
stone age NANDs with 256 bytes pages, as well as iron age NANDs with 512
bytes per page and up to 8MiB page size.

It is with great sorrow that I inform you that the museum is being
decommissioned. The MTD subsystem is out of budget for Kconfig options and
already has too many of them, and there is a general kernel trend to
simplify the configuration menu.

We remove the stone age exhibits along with closing the museum

REMARK Don't apply this part from upstream:

Some of the iron age ones are transferred to the regular NAND depot.
Namely, only those which have unique device IDs are transferred, and the
ones which have conflicting device IDs are removed.

Changes in v3:
- Use commit sha1 with 13 digits.
- Wrap commit description to a maximum of 75 chars.

Changes in v2:
- Use short-commit form.
- Remove linux info. Uboot seems that backport without add this
  extra information.
