Commit 5b4f4253c1
("drivers: flash: add Nordic JEDEC QSPI NOR flash driver")'
added SPI2 pin properties wich are in conflict with CS pin
of the SPI3, pin D9, and pin D8 routed to Arduino connector
of the pca10056 board. This change has broken any shield
support on this board.
Route SPI2 node pin properties to MX25R64 device.
