Remove XBOX Controller Mappings from Robot.java

[dlaflotte]

We should stick with one standard. We've currently mapped POV hat for the operator controller in Robot Container (RobotContainer.java:120) and should push the POV mapping for driver controller(Robot.java:106) into RobotContainer and follow the same mapping paradigm.
