I've tried my best to go through the remaining similar-looking code,
but the rest seems fine (I might've missed something though).

The only thing I reacted on was that in intel_runtime_resume() the call
to intel_init_pch_refclk() is conditional on IS_GEN6(), but none of the
other invocations of intel_init_pch_refclk() are.  The commit message
doesn't seem to provide a sufficient explanation for why this is so.
