nand: Introduce CONFIG_SYS_NAND_SELF_INIT
This allows a driver to run code between nand_scan_ident() and nand_scan_tail(), among other things. See the additions to doc/README.nand for details. To allow a gradual transition, Boards that don't set CONFIG_SYS_NAND_SELF_INIT will still be initialized the old way, but new drivers should not require this, and existing drivers should be converted when convenient.
