[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.
