drm/i915: Remove variable length arrays from sseu debugfs printers

In order to enable -Wvla to prevent new variable length arrays being
used in i915.ko, we first must remove the existing VLA. Inside
i915_print_sseu_info(), VLA are used as the actual size of the sseu
depends on platform. Replace the VLA with the maximum required.
