[PATCH 6/7] Documentation: atmel-quadspi: add binding file for Atmel QSPI driver

[Cyrille Pitchen]

Hi Sergei,

thanks for the review. For the next series I've removed all references to
"qspi" in the node example but the one from the compatible string.
I've also removed the leading 0 in the size of the second memory region.

Best Regards,

Cyrille
