soc/intel/cmn/cnvi: Drop CNIP ACPI method

This method is used in the Intel/AMI reference code to verify
that the device is present (vendor ID != 0xFFFFFFFF), but that's
neither used nor needed here, as coreboot only generates SSDT
code for devices which are actually present.

TEST=build/boot Linux, verify no ACPI issues after dropping
