Merge branches 'acpi-cppc' and 'acpi-dptf'

Merge new ACPI CPPC driver updates and new Raptor Lake DPTF device
IDs for 5.17-rc1.

* acpi-cppc:
  ACPI: CPPC: Drop redundant local variable from cpc_read()
  ACPI: CPPC: Fix up I/O port access in cpc_read()

* acpi-dptf:
  ACPI: DPTF: Support Raptor Lake
