Bluetooth: hci_bcm: Add support for MINIX Z83-4 based devices
The MINIX NEO Z83-4 and MINIX NEO Z83-4 Pro devices use an AP6255 chip for
wifi and bluetooth. Bluetooth requires an ACPI device id of BCM2EA4 with
BCM4345 rev C0 firmware.
This patch adds the device id and to use trigger type IRQF_TRIGGER_FALLING
as defined by 'GpioInt' in the ACPI DSDT table:
