[PATCH v2 1/2] Bluetooth: hci_bcm: Add support for MINIX Z83-4 based devices

[Ian W MORRISON <ianwmorrison@gmail.com>]

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.
