Bluetooth: hci_bcm4377: Use generic power management

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.
