This doesn't give the board driver a chance to run before the bad block
scan, though.  The MTD code itself does (nand_scan_ident and nand_scan_tail,
around which nand_scan is a wrapper), but the u-boot glue code doesn't
currently let board drivers take advantage of that.

I'd like to transition away from having a centralized nand_init(), and
instead have the board drivers call nand_scan*() themselves.
