[PATCH v4 3/4] dt-bindings: i2c: imx: Add properties and use unevaluatedProperties

[Krzysztof Kozlowski]

Additional properties actually might appear (e.g. power-domains) so
describe all typical properties, reference generic i2c schema and use
unevaluatedProperties to fix dtbs_check warnings like:

  arch/arm64/boot/dts/freescale/imx8mn-evk.dt.yaml: i2c at 30a20000:
    '#address-cells', '#size-cells', 'pmic at 25' do not match any of the regexes: 'pinctrl-[0-9]+'

Signed-off-by: Krzysztof Kozlowski <krzk at kernel.org>

Changes since v3:
1. Drop address/size cells

Changes since v2:
1. None

Changes since v1:
1. Add more properties and include /schemas/i2c/i2c-controller.yaml#
