    mtd: nand: remove unused ->init_size() hook
    
    The ->init_size() hook was introduced to let NAND controller drivers
    support NAND devices that could not be described in the nand_ids table.
    Since then, the core has added support for extended-id parsing and
    full-id description, thus allowing to describe pretty much all existing
    NANDs.
    Moreover, this hook is not used by any mainline driver, and should not be
    used by new drivers, because detecting the NAND chip is not something
    controller specific.
