intel_scu_ipc: Convert to use struct device *
Switch the code to use struct device * instead of struct pci_dev * since there is no reason to access PCI related features in the driver. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Darren Hart <dvhart@linux.intel.com>
