[PATCH BlueZ] sixaxis: DS4: use 0x12 cmd to get device bdaddr

[Marek Czerski <ma.czerski@gmail.com>]

This change is required for Esperanza EGG109k ps controller clone.
EGG109k looks like PS3 controller but presents itself to the system
as PS4 controller. It does not respond to 0x81 command.
Command 0x12 contains both the device mac address as well as
configured host mac address, so it can be used to query
both. Kernel driver also uses 0x12 command for that.
