x86: tangier: Add Bluetooth to ACPI table
As defined on reference board followed by Intel Edison a Bluetooth
device is attached to HSU0, i.e. PCI 0000:04.1.
Describe it in ACPI accordingly.
Note, we use BCM2E95 ID here as one most suitable for such device based
on the description in commit message of commit 89ab37b489d1
("Bluetooth: hci_bcm: Add support for BCM2E95 and BCM2E96")
in the Linux kernel source tree.
