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
Neil Armstrong (2):
base: dma-coherent: Add DT property for non exclusive shared-dma-pool
devicetree: reserved-memory: document the optional no-exclusive parameter
