Edward O'Callaghan b40c600914 mainboard/hatch: Fix puff DP output on cold boots 
Wait for HPD DP unless HDMI is plugged.

Some Type-C monitors do not immediately assert HPD. If we continue
to boot without HPD asserted, Depthcharge fails to show pictures
on a monitor even if HPD is asserted later.

Similar to that of b:72387533 however our DP&HDMI are beind a MST.
See commit d182b63347 on how this was done for mainboard/fizz.

BUG=b:147992492
BRANCH=none
TEST=Verify firmware screen is displayed even when a type-c monitor
does not immediately assert HPD. Verify if HDMI monitor is connected,
AP does not wait (and firmware screen is displayed on HDMI monitor).
