ANDROID: dt-bindings: interconnect: Add generic PWR_ST tags

Add generic PWR_ST tags that can be used when there are more logical
aggregation buckets than just AMC, WAKE, and SLEEP.

Also add binding for QCOM_ICC_TAG_PERF_MODE, which can be used with
icc_set_tag() to indicate that the path should use latency-optimized
settings for each node in the path if supported.
