Krzysztof Kozlowski's @canonical.com email stopped working, so switch to
generic @kernel.org account for all Devicetree bindings.

In new Exynos SoCs (like Exynos850) where HSI2C is implemented as a
part of USIv2 block, there are two clocks provided to HSI2C controller:
- PCLK: bus clock (APB), provides access to register interface
- IPCLK: operating IP-core clock; SCL is derived from this one
Both clocks have to be asserted for HSI2C to be functional in that case.
Modify bindings doc to allow specifying bus clock in addition to
already described operating clock.

Convert Samsung Exynos High Speed I2C bindings doc to DT schema format.
Changes during bindings conversion:
1. Added missing required clock properties (driver fails when it's
unable to get the clock)
2. Removed properties and descriptions that can be found in
schemas/i2c/i2c-controller.yaml [1]
3. Fixed the example so it can be validated by dtschema
