drm/i915/skl: Adjust the display engine interrupts

Browse Source 
To accomodate the extra planes, the bit definitions were shuffled around
a bit.

v2: Rebase on top of the for_each_pipe() change adding dev_priv as first
    argument.
v3: Rebase after yet another change int that area (done with wiggle)
