bc12: pi3usb9201: Save supplier to update charge managerstabilize-12060.Bstabilize-12058.Bstabilize-12054.B

When bc1.2 detection is completed, it will update the available charge
for the supplier type which was detected. When bc1.2 is powered down
(upon CC detach), the charge manager needs to be informed that the
available charge for this supplier type is 0,

This CL modifies the pi3usb9201 driver to store the most recent bc1.2
detection supplier type for each port. When the bc1.2 chip is powered
down, then the charge manager can be properly updated.
