commit 39646f29b100566451d37abc4cc8cdd583756dfe upstream.
Some Bluetooth controllers lack persistent storage for the device
address and instead one can be provided by the boot firmware using the
'local-bd-address' devicetree property.
The Bluetooth devicetree bindings clearly states that the address should
be specified in little-endian order, but due to a long-standing bug in
the Qualcomm driver which reversed the address some boot firmware has
been providing the address in big-endian order instead.
Add a new quirk that can be set on platforms with broken firmware and
use it to reverse the address when parsing the property so that the
underlying driver bug can be fixed.
Fixes: 5c0a1001c8be ("Bluetooth: hci_qca: Add helper to set device address")
