[U-Boot] x86: SPI flash broken with SPI NOR

[Simon Glass]

Hi Bin,

I find that 'sf test 0 1000' does not work anymore since this commit:

c4e8862308 mtd: spi: Switch to new SPI NOR framework

Have you seen any problems? This seems to prevent proper SPI flash writing
(not sure about reading).

Also, it seemed to increase code size on samus by >2KB.

Regards,
Simon
