All Ingenic SoCs starting from the JZ4725B support OSD mode.
In this mode, two separate planes can be used. They can have different
positions and sizes, and one can be overlayed on top of the other.
v2: Use fallthrough; instead of /* fall-through */
v3: - Add custom atomic_tail function to handle case where HW gives no
VBLANK
- Use regmap_set_bits() / regmap_clear_bits() when possible
- Use dma_hwdesc_f{0,1} fields in priv structure instead of array
- Use dmam_alloc_coherent() instead of dma_alloc_coherent()
- Use more meaningful 0xf0 / 0xf1 values as DMA descriptors IDs
- Add a bit more code comments
