ANDROID: hid: steam: remove BT controller matching

The driver hid-steam is only meant to support the USB mode and the
wireless dongle mode. It was never meant to work over the BT using the
beta version of the firmware of the steam controller.

In the BT mode, the controller works as a "lizard-mode" device by
default. It probably needs to have a special command to activate the
controller mode, but for simplicity, we just revert to the upstream
state of having the hid-generic driver take care of it.
The lizard mode can probably be worked around in the BT stack.

Bug: 147434575
Test: connect Steam controller over BT (press steam button and "Y" key
simultaneously) and make sure that the mouse device shows up as a
cursor. You can use the trigger buttons to generate left and right mouse
clicks.
Test: compare against the upstream version, and check that it's missing
the define for STEAM_CONTROLLER_BT and the matching for the product ID
1106.
