Revert "i965: Advertise a line width of 40.0 on Cherryview and Skylake."
This reverts commit f3b709c0. The "dEQP-GLES3.functional.rasterization.fbo.rbo_multisample_4. interpolation.lines_wide" test appears to be broken on Cherryview when we expose line widths greater than 12.0. I'm not sure why. For now, just go back to the limits we used on older platforms. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=90902 Acked-by:Matt Turner <mattst88@gmail.com>
