Bluetooth: hci_bcm4377: Use generic power management

Browse source 
Switch to the generic PCI power management framework and remove legacy
callbacks like .suspend() and .resume(). With the generic framework, the
standard PCI related work like:
        - pci_save/restore_state()
        - pci_enable/disable_device()
        - pci_set_power_state()
is handled by the PCI core and this driver should implement only
hci_bcm4377 specific operations in its respective callback functions.
