platform/x86/intel-uncore-freq: Rename instance_id

Browse source

The "instance" word has a specific meaning in TPMI. It is a physical
index related to compute dies and IO dies present on a single TPMI
partition (which is also a single TPMI device). It's used for mapping
MMIO blocks for direct TPMI register access.

The currently used "instance_id" uncore_data struct field is a
sequentially generated value that's used for appending to uncore
directories inside the /sys/devices/system/cpu/intel_uncore_frequency
directory. It has no relation to the physical TPMI elements.
