This patch adds code that I think was lost when it was applied the commit
5988af2319781bc8e0ce418affec4e09cfa77907 - mtd: Flex-OneNAND support
Test case:
1. Stress a jffs2 filesystem using
bonnie++ -u 0:0 -s 32 -m 16 -r 16
2. dmesg shows various 'Header CRC failed' errors like:
Header CRC failed on REF_PRISTINE node at 0x1e81315c: Read 0x000000e0,
calculated 0x564fc9e8
Tested on IGEP v2 board with a Muxed OneNAND(DDP) 512MB 1.8V 16-bit (0x58)
with 2 planes from Numonyx and CONFIG_MTD_ONENAND_2X_PROGRAM set to y
