Revert "i965: Advertise a line width of 40.0 on Cherryview and Skylake."

Browse source 
This reverts commit f3b709c0ac.

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.
