drivers/i2c/generic: Support additional device properties
Add support for providing additional free form device properties via
devicetree in order to make this driver suitable for kernel drivers
that need additional board-specific device properties.
This currently allows adding up to 10 additional properties to a device.
BUG=b:63413023
TEST=manual testing to ensure that newly added properties are in SSDT
