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.
