"jedec,spi-nor" is used by Linux for many boards with spi flash. In fact according to the binding documentation this must be included for any SPI NOR flash that can be identified by the JEDEC READ ID opcode (0x9F). Make device trees more portable between Linux an U-Boot by supporting "jedec,spi-nor" in addition to the U-Boot specific "spi-flash".

This fixes my issues with the spi speed selection on db-88f6820-amc. I didn't find anything in the commit message from the initial implementation saying that "jedec,spi-nor" was omitted intentionally so I've settled on this instead of updating armada-385-amc.dts.
If there is a good reason not to make this change I'm happy to submit a patch that just updates armada-385-amc.dts.
At this point try to use spi-flash in dts since we're in WIP for spi-nor support once ie in-place then only we have sync the compatible of what Linux is using.
thanks!
