Subject: [PATCH v1 1/1] ASoC: Intel: catpt: Carefully use PCI bitwise constants

PM constants for PCI devices are defined with bitwise annotation.
When used as is, sparse complains about that:

  .../catpt/dsp.c:390:9: warning: restricted pci_power_t degrades to integer
  .../catpt/dsp.c:414:9: warning: restricted pci_power_t degrades to integer

Force them to be u32 in the driver.
