drivers/i2c/generic: Enable support for adding PowerResource for device
Add support to allow a device to define PowerResource in its SSDT AML
code. PowerResouce ACPI generation expects SoC to define the
callbacks for generating AML code for GPIO manipulation.
Device requiring PowerResource needs to define following parameters:
1. Reset GPIO - Optional, GPIO to put device into reset or take it out
of reset.
2. Reset delay - Delay after reset GPIO is de-asserted (default 0).
3. Enable GPIO - Optional, GPIO to enabled device.
4. Enable delay - Delay after enable GPIO is asserted (default 0).
