While this property wants to express a capability of the hardware, this is only used by the driver itself to vary the DMA bits during probe. Different hardware shall instead have different compatible strings. Following the driver cleanup and the introduction of a specific compatible string for the APDMA IP version found in MT6795, set the "mediatek,dma-33bits" vendor property as deprecated.
