drm/tilcdc: Write DMA base and ceiling address with single instruction Write DMA base and ceiling address with a single instruction, if available. This should make it more unlikely that LCDC would fetch the DMA addresses in the middle of an update. Having bad combination of addresses in dma base and ceiling (e.g base > ceiling) can cause unpredictaple behavior in LCDC.
