Todd Broch cadce20c1a pd: Add DFP parsing for alternate mode status & attention. ...

Once alternate mode is entered the DFP will make an initial status
request to the UFP.  Future status changes on the UFP are then sent to
the DFP via the attention command.  This VDM consists of the VDM
header plus another VDO containing mode specific information.

CL adds ability of DFP to consume the attention VDMs status message
and in the case of DisplayPort SID toggle the necessary HPD gpio
accordingly.

BRANCH=samus
BUG=chrome-os-partner:30645
TEST=manual, for DFP w/ HPD over CC see HPD toggle correctly without
manually driving it providing cable connected when AMA is inserted.
