    drm/i915: Do a fuller init after reset · 3d57e5bd

    I had this lying around from he original PPGTT series, and thought we
    might try to get it in by itself.
    
    It's convenient to just call i915_gem_init_hw at reset because we'll be
    adding new things to that function, and having just one function to call
    instead of reimplementing it in two places is nice.
    
    In order to accommodate we cleanup ringbuffers in order to bring them
    back up cleanly. Optionally, we could also teardown/re initialize the
    default context but this was causing some problems on reset which I
    wasn't able to fully debug, and is unnecessary with the previous context
    init/enable split.
    
    This essentially reverts:

        drm/i915: don't call modeset_init_hw in i915_reset
    
    It seems to work for me on ILK now. Perhaps it's due to:
