TCPMv2: Separate DPM and DP from PE
Create separate modules representing DisplayPort (which decides whether
and how we can set up the DP alt mode) and the Device Policy Manager
(which decides whether we should). The end goal is to have essentially
all code with DP-specific decisions or information in the DP module and
all code with DPM-specific decisions or information in the DPM module.
This will allow the PE to map as directly as practical to its behaviors
defined in the PD spec.
Essentially detach PE_DO_PORT_DISCOVERY from the rest of the PE state
machine in preparation for deleting it.
This change paves the way for
1) Allowing the AP to drive mode entry and
2) Allowing new alt modes to be supported via largely self-contained
modules.
BUG=b:155890173
TEST=Attach DP dongle; observe discovery and DP setup via Twinkie
BRANCH=none
