Bluetooth: hci_bcm: Add ACPI and PM support

These patches move PM support from rfkill-gpio to hci_uart module. On, off, suspend and resume functions are supported. They also parse the ACPI entry to find initial UART baud rate.

v4->v5:
- Rename parameter and variable of bcm_suspend and bcm_resume

v3->v4:
- Fix commit message of rfkill-gpio patch

v2->v3:
- Add bcm_device existance check as driver can be unbound and reference in bcm_data may be invalid
- Add explanation of retrieval of bcm_device corresponding to tty in use
- Rename variables : ptr -> p, device_list -> bcm_device_list,

                     device_list_lock -> bcm_device_list_lock

- Remove BCM2E39 in rfkill-gpio.c instead of making it conditional

v1->v2:
- Add BCM2E67 device in acpi_device_id table
- Add suspend/resume functions
