drm/radeon/kms: add ioport register access
This is required for the NB_MISC regs on rs780/rs880 which means HDMI/DVI/DP ports using PCIEPHY won't work without it. It might also help with s/r (asic init) issues on other atombios cards. Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=28774 and similar issues reported by Alberto Milone.
