HID: Add support for Sony PS3 BD Remote Control
The Sony PS3 Blue-ray Disc Remote Control used to be supported by the BlueZ project's user space, but the code that handled it was recently removed as its functionality conflicted with a real HSP implementation and the mapping was thought to be better handled in the kernel. This is a port of the mapping logic from the fakehid driver by Marcel Holtmann to the in-kernel HID layer. We also add support for the Logitech Harmony Adapter for PS3, which emulates the BD Remote.
