Query the port partner's SVIDs when the DisplayPort driver sysfs
is not recognized so that the USB HAL can identify whether or not
the port partner supports Thunderbolt.
Test: manual verification on device - test to see that cableStatus
is set to NOT_CAPABLE on hub that supports Thunderbolt but not
DisplayPort Alt Mode. Then verify that device not capable of being
a DisplayPort sink but does support Thunderbolt does not trigger
this status.

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.

If Usb.cpp cannot write a zero value to the USB_DATA_PATH file, display
the message of "Not able to turn off usb connection notification".
Test: refactoring CL. Existing tests still pass.

Better enforces that only one DisplayPort poll thread should be
active at once. If a new call to setup is made from additional
bind uevents before a disconnect occurs, tells the old thread
to shutdown and awaits signaling before a new worker thread spins
up.

When booting check whether displayport driver has been probed and
signal hpd events as needed. Pin config and orientation needs to
be queried before signalling hpd.
