It appears that Atmel has reverted this in later chips, like the
AT49BV642D. Updated patch below, if you still want it. Please disregard
the jedec_probe patch as I've got AT49BV6416 working in CFI mode now.

This patch depends on "MTD: Convert Atmel PRI information to AMD
format" which I just submitted, as it needs the definition

I've added this patch to my tree.
