commit e50af8332785355de3cb40d9f5e8c45dbfc86f53 upstream.
Only Coffeelake should use Cannonlake regmap other than Cannonlake platform. This allows Coffeelake special handling only when there is no matching PCI device and default reg map selected as per CPUID is for Sunrisepoint PCH. This change is needed to enable support for newer SoCs such as Icelake.
