Merge branch 'icc-rpm' into icc-next

This patch set is to support bucket in icc-rpm driver, so it implements
the similar mechanism in the icc-rpmh driver.

It uses interconnect path tag to indicate the bandwidth voting is for
which buckets, and there have three kinds of buckets: AWC, WAKE and
SLEEP, finally the wake and sleep bucket values are used to set the
corresponding clock (active and sleep clocks).  So far, we keep the AWC
bucket but doesn't really use it.
