dt-bindings: power: Add Allwinner D1 PPU
The Allwinner D1 family of SoCs contain a PPU power domain controller
separate from the PRCM. It can power down the video engine and DSP, and
it contains special logic for hardware-assisted CPU idle. Other recent
Allwinner SoCs (e.g. TV303) have a PPU with a different set of domains.
