mtd: sm_ftl: remove CONFIG_SM_FTL_MUSEUM and make it always on
The sole purpose of this setting was to avoid a dependency on MTD_NAND. Now that we can depend on MTD_NAND_ECC without pulling in all the rest of the NAND code, we might as well do so unconditionally.

324 help
325 Very old SmartMedia cards need ECC to be calculated in the FTL.
326 Such cards are very rare, thus enabling this option is mostly useless.
327 Also this support is completely UNTESTED.
