drivers/i2c/cs42l42: Add driver for generating device in SSDT

This driver uses the ACPI Device Property interface to generate
the required parameters into the _DSD table format expected by
the kernel.

This was tested on the octopus/variants/fleex mainboard to ensure
that the SSDT contained the equivalent parameters that are provided
by the current DSDT object.
