[MTD] [NOR] Fix Intel CFI driver for collie flash
collie seems to contain LH28F640BF flash chips. According to http://sharp-world.com/products/device/flash/pdf/*FUM00701*@E.pdf (page 83) if they have 0x51 of Extended Query Table (number of hardware partitions) set to zero, they have a single fixed partition. This patch makes those chips work. Signed-off-by: Thomas Kunze <thommycheck@gmx.de> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
