dt-bindings: arm: sunxi: Add several MBUS compatibles All of the sunxi SoCs since at least the A33 have a similar structure for the MBUS and DRAM controller, but they all have minor differences in MBUS port assignments and DRAM controller behavior. Give each SoC its own compatible.

dt-bindings: arm: sunxi: Default to the full MBUS binding Some older SoCs use a deprecated MBUS binding with some clocks missing. Currently, new SoCs must opt in to the complete binding. This should be the default, so new SoCs do not accidentally use the deprecated version.

dt-bindings: arm: sunxi: Add H5 MBUS compatible The H5 SoC has a MBUS very similar to the H3 SoC, but it has a smaller MDFS divider range (1-4 instead of 1-16). Add a separate compatible for this variant.

dt-bindings: arm: sunxi: Expand MBUS binding The MBUS provides more than address translation and bandwidth control. It also provides a PMU to measure bandwidth usage by certain masters, and it provides notification via IRQ when they are active or idle. The MBUS is also tightly integrated with the DRAM controller to provide a Memory Dynamic Frequency Scaling (MDFS) feature. In view of this, the MBUS binding needs to represent the hardware resources needed for MDFS, which include the clocks and MMIO range of the adjacent DRAM controller. Add the additional resources for the H3 and A64 compatibles, and a new example showing how they are used.
