usb: typec: hd3ss3220: Enable VBUS based on ID pin state

There is a ID pin present on HD3SS3220 controller that can be routed
to SoC. As per the datasheet:

"Upon detecting a UFP device, HD3SS3220 will keep ID pin high if VBUS is
not at VSafe0V. Once VBUS is at VSafe0V, the HD3SS3220 will assert ID pin
low. This is done to enforce Type-C requirement that VBUS must be at
VSafe0V before re-enabling VBUS"

Add support to read the ID pin state and enable VBUS accordingly.
