There is no reason not to use the Linux "jedec,spi-nor" binding in u-boot.
This patch adds this compatible into sf_probe and will avoid changing the
device tree files to add a u-boot specific compatible to probe a spi flash.
This change is needed to enable SPI NOR Flash support using the non-modified
device tree file for Amlogic Meson GX SoC based boards.

This is definitively a move in the right direction! I was only days away
from sending this myself ;-)

I would still need more changes to U-Boot to boot the Linux socfpga
devicetrees without patches (they have compatible = "n25q256a" etc.),
but then again, maybe it's easier to change the Linux ones to include
"jedec,spi-nor" than trying the effort of changing U-Boot here...
