Neil Armstrong ffd4c7c2ec dts: switch spi-flash to jedec, spi-nor compatible
There is no reason not to use the Linux "jedec,spi-nor" binding in U-Boot
dts files. This compatible has been added in sf_probe, let use it.

This patch switches to jedec,spi-nor when spi-flash is used in the DTS
and DTSI files, and removed spi-flash when jedec,spi-nor is already
present.

The x86 dts are switched in a separate commit since it depends on a change
in fdtdec.
