Otherwise we'll read registers that return 0xffffffff, trigger some WARNs, think CRT is actually connected (because certain bits are 1), and fail the drm-resources-equal testcase! Tested on a SNB machine with runtime PM support (which is not upstream yet, but is already on my public tree at freedesktop.org, and will hopefully eventually become upstream).
