Another possibility (for future work, maybe) is that you allocate a
smaller buffer that fits what you need for "device detection" (I presume
it's just for ONFI parameter page commands?), then reallocate the buffer
between nand_scan_ident() and nand_scan_tail() according to page size.
There are some other similar buffers throughout NAND that use a fixed
NAND_MAX_OOBSIZE and NAND_MAX_PAGESIZE.
