drivers/intel/mipi_camera: Add ACPI entry to provide silicon type info
Add entry in ACPI table under IPU device to provide silicon type
information to IPU driver. IPU kernel driver can decide the type of
firmware to load based on this information.
BUG=b:207721978
BRANCH=none
TEST=Check for the ACPI entry in the SSDT after booting to kernel
