Tha's kinda what the debugfs file is for, to check whether the registers
have the right values in an easy way. Caveat though, there are some errata
on snb that you can't read back stuff from the render ring registers. And
experience shows that if you frob these too often, they start to read
garbage (but writes still work as they should, strangely).

i915_gem_init_hw is called for both initial setup and resum, and the reset
code is a few hunks up. Reset tested with my gpu hangman.
