Atmel SAMA5D2 QuadSPI driver was moved from mtd to spi subsystem,
this change is just moving DT-binding documentation.

-* Atmel Quad Serial Peripheral Interface (QSPI)

-Required properties:
-- compatible:     Should be "atmel,sama5d2-qspi".
-- reg:            Should contain the locations and lengths of the base registers
-                  and the mapped memory.
-- reg-names:      Should contain the resource reg names:
-                  - qspi_base: configuration register address space
-                  - qspi_mmap: memory mapped address space
-- interrupts:     Should contain the interrupt for the device.
-- clocks:         The phandle of the clock needed by the QSPI controller.
-- #address-cells: Should be <1>.
-- #size-cells:    Should be <0>.
