drm/i915: W/A for underruns with WM1+ disabled on icl
Disabling WM1+ on ICL causes tons of underruns with
linear/X-tiled framebuffers. We can avoid this by flipping
on a chicken bit affecting the way the hw fill the FIFO.
This may not be the final solution but should hopefully
avoid some underruns in the meantime.
v2: Apparently PIPE_CHICKEN is icl+ only
