Subject: [PATCH] platform/x86: intel_speed_select_if: Use devm_ioremap_resource

Replace devm_ioremap() with devm_ioremap_resource() by defining a
resource.

No functional impact is expected.

This patch requires merge of series "Minor SST optimizations",
particularly
platform/x86: intel_speed_select_if: Remove hardcoded map size
Can be differed to 6.8 cycle.
If I repost the series after reviews, I will include as part of the
series.
