The WCN6855 firmware on the Lenovo ThinkPad X13s expects the Bluetooth
device address in big-endian order when setting it using the
EDL_WRITE_BD_ADDR_OPCODE command.
Presumably, this is the case for all non-ROME devices which all use the
EDL_WRITE_BD_ADDR_OPCODE command for this (unlike the ROME devices which
use a different command and expect the address in little-endian order).
Reverse the little-endian address before setting it to make sure that
the address can be configured using tools like btmgmt or using the
'local-bd-address' devicetree property.
Note that this can potentially break systems with boot firmware which
has started relying on the broken behaviour and is incorrectly passing
the address via devicetree in big-endian order.
The only device affected by this should be the WCN3991 used in some
Chromebooks. As ChromeOS updates the kernel and devicetree in lockstep,
the new 'qcom,local-bd-address-broken' property can be used to determine
if the firmware is buggy so that the underlying driver bug can be fixed
without breaking backwards compatibility.
Set the HCI_QUIRK_BDADDR_PROPERTY_BROKEN quirk for such platforms so
that the address is reversed when parsing the address property.
