[ALSA] Various fixes for suspend/resume of ALSA PCI drivers 



- Check the return value of pci_enable_device() and request_irq()
  in the suspend.  If any error occurs there, disable the device
  using snd_card_disconnect().
- Call pci_set_power_state() properly with pci_choose_state().
- Fix the order to call pci_set_power_state().
- Removed obsolete house-made PM codes in some drivers.
