Enable support for nrfx QSPI driver with EasyDMA.

Device driver initialization priority.

int "Page size to use for FLASH_LAYOUT feature"
default 65536
help
When CONFIG_FLASH_PAGE_LAYOUT is used this driver will support
that API. By default the page size corresponds to the block
size (65536). Other option include the sector size (4096).
config NORDIC_QSPI_NOR_STACK_WRITE_BUFFER_SIZE
int "Size of a stack-based buffer to support writes from NVMC"
default 0
help
The QSPI peripheral uses DMA and cannot write data that is
read from the internal flash. A non-zero value here enables
a stack buffer into which data is copied to allow the write
to proceed. Multiple transfers will be initiated if the
data is larger than the configured limit. Must be a
multiple of 4. The feature is disabled when set to 0.
