dt-bindings: i2c: apple,i2c: Add power-domains property
This will bind to the PMGR pwrstate nodes that control power/clock gating to SoC blocks. The i2c driver doesn't do runtime-pm yet, so initially this will just keep the domain on permanently. Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Hector Martin <marcan@marcan.st>
