dm: add ACPI info for ipu pass-through
IPU devices are using I2C device with physical BDF 0:16.0. The I2C controller has the dependency on ACPI info. This patch is to add ACPI info for the I2C controller and the two IPU devices that are under the scope of I2C. Note: This patch is specific for GP platform.
