sna/gen7: Limit threads on HSW GT1
For whatever reason, it seems that for HSW GT1 we cannot specify the
maximum value of the field and leave it to the hardware to clamp the
value to the maximum supported. The impact should be zero other than the
possibilty it workarounds an issue if the hardware doesn't apply the
limit.

Latest git containing these two commits from <a href="show_bug.cgi?id=90725#c42">Comment 42</a> and <a href="show_bug.cgi?id=90725#c43">Comment 43</a>
<span class="quote">> commit b0aa9d349ddf727dc544bc46d066f990d3e42776

fixed both issues (the crashing issue and the display issue of <span class=""><a href="attachment.cgi?id=116237" name="attach_116237" title="Display issue when not using debug=full">attachment
116237</a> <a href="attachment.cgi?id=116237&action=edit" title="Display issue when not using debug=full">[details]</a></span> )
So I can say I didn't face any issue yet with kernel I915_BIT_6_SWIZZLE_9_10_17
+ git as of today 11am GMT whether I use --enable-debug=full or don't set
debug=full</pre>
