Expose DMA_MEMORY_EXCLUSIVE through shared-dma-pool
v3 cover Expose DMA_MEMORY_EXCLUSIVE through shared-dma-pool
The shared-dma-pool dt node only exposes exclusive memory, but in order to export non-exclusive coherent memory, add the no-exclusive property and document it.
v3: use correct of_get_flat_dt_prop helper
v2: simplify patch by looking for DT attribute in callback

base: dma-coherent: Add DT property for non exclusive shared-dma-pool
devicetree: reserved-memory: document the optional no-exclusive parameter
