TCPMv2: Allow DFP ALT-DP mode without chipset task
This CL guards checks related to AP power state with a check for
chipset task. This is required for boards which might still want to do
ALT-DP mode, but do not have an AP, such as a type-c dock.
BUG=b:175660576
BRANCH=None
TEST=Verified on quiche that C1 port will enter alt-dp mode as DFP
