drm/i915: Consolidate condition for Wa_22011802037
[ Upstream commit 28c46feec7f8760683ef08f12746630a3598173e ]
The workaround bounds for Wa_22011802037 are somewhat complex and are
replicated in several places throughout the code. Pull the condition
out to a helper function to prevent mistakes if this condition needs to
change again in the future.
