Add the conditionals to enable rumble, battery reporting, LED and touchpad
support for the Dualshock 4 in Bluetooth mode.
Add dualshock4_set_operational_bt to initialize the controller to the proper
operational state.
Signed-off-by: Frank Praznik <frank.praznik@xxxxxxxxx>
---
v3 adds a DUALSHOCK4_CONTROLLER macro for conditional cases where the
connection type is irrelevant as well as dualshock4_set_operational_bt to
explicitly initialize the controller instead of the device state being set as a
side effect of initializing the LED system.
