Added USB detection + power control to the bottom of @scholbert's collage.

This shows where the ANX7688 looks at CC1/CC2 and DCIN for USB C channel configuration detection, while the AXP803 looks at DP/DM for (dumb) charger detection. Shows where the ANX7688 can decide to turn on VBUS_CTRL, which affects both the LPW5206 and the PMIC.

Even if the ANX7688 says it's ok to use DCIN, the PMIC can still decide not to use it for other reasons.

Thanks @smaeul for explaining how this works!
