sama5d4_xplained has an optional on-board serial DataFlash (AT25DF321A),
which does not come populated on board by default. Mark it as disabled
to avoid the following probe error:
spi-nor spi0.0: unrecognized JEDEC id bytes: 00 00 00 00 00 00

What about keeping SPI enabled and just having the status of m25p80 as disabled: honestly, I don't know if it works and if it's desirable, but might be closer to reality.

Tell me what you think.
