ACPI / i915: replace open-coded _DSM code with helper functions Use helper functions to simplify _DSM related code in i915 driver. Function intel_dsm() is used to check functions supported by ACPI _DSM method, but it has strange check for special value 0x80000002. After digging into nouveau driver, I think the check is copied from nouveau driver and is useless for i915 driver, so remove it.
