Use a EC to PD host command to notify the PD MCU when a battery is present and charged enough that it is ok to negotiate for a higher power. The PD MCU will not negotiate until the host command is received, which allows the system to be powered without a battery or with a dead battery with 5V. BUG=chrome-os-partner:28611 BRANCH=none TEST=Tested on a samus: 1) Tested the normal case of battery charged and plugged in. When charger is plugged in, the device immediately starts negotiating for 20V and starts charging. 2) Tested with no battery. Plug in a charger, samus boots and stays alive. VBUS measured at 5V. When a battery is plugged in, device negotiates for 20V and starts charging. 3) Tested dead battery by taking a battery with no charge, and plugging in zinger. Everything boots, but PD does not negotiate for power. Then when battery reaches 1%, PD negotiates and zinger switches to 20V without causing a reboot.
