The optional 'dmacap,memcpy' DT property tells the Atmel QSPI controller
driver to reserve some DMA channel then to use it to perform DMA
memcpy() during data transfers. This feature relies on the generic
bounce buffer helper from spi-nor.c.

driver to reserve some DMA channel then to use it to perform DMA
