ACPI: NHLT: Streamline struct naming
Few recently introduced structs are named 'nhlt2' instead of 'nhlt' to avoid naming conflicts. With duplicate types gone, the conflicts are no more. Signed-off-by: Cezary Rojewski <cezary.rojewski@intel.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
