Subject: [PATCH 01/26] drm/xe/pf: Remove GuC version check for migration support

Since commit 4eb0aab6e4434 ("drm/xe/guc: Bump minimum required GuC
version to v70.29.2"), the minimum GuC version required by the driver
is v70.29.2, which should already include everything that we need for
migration.
Remove the version check.
