drm/i915: Consolidate condition for Wa_22011802037

[ Upstream commit 28c46fee ]

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.
