Adds functionality for enabling and disabling DisplayPort Alt Mode
on the port through enableUsbData in the USB HAL to comply with USB
restrictions for heightened security mode.
Test: manual test on device - use enableUsbData dumpsys command to
turn off DisplayPort and then turn it back on while connected to a
partner sink.
