I gave this a quick test on all of the SI asics and the various
monitors I had available and it looks good.  A few minor patches I
noticed are attached.  If they look good to you, I'll squash them into
the series when I commit it.  I've pushed it to my fdo tree as well:
https://cgit.freedesktop.org/~agd5f/linux/log/?h=si_dc_support

Thanks!
