drm/i915: shorten debugfs output simple attributes

    drm/i915: use simple attribute in debugfs routines

made i915_next_seqno debugfs entry to crop it's output
if returned value was large enough. Using simple_attr
will limit the output to 24 bytes.

Fix is to strip out preamples on all simple attributes
that have one.

v2: Fix all simple attributes (Daniel Vetter)
