tcpci: Only drive one CC line when attached
Some of the NCT38XX driver code was more generic TCPCI
than specific to the chip. So moved a number of the
functions over to be generically handled.
In doing this I propagated the idea of tri-state
polarity. It is now either NORMAL, FLIPPED, or NONE
for unattached. This is needed for the generic handling
of correctly setting CC. This required changing the
polarity from NONE to the appropriate detected polarity
when in auto toggle.
tcpci_tcpm_set_cc will now only set a single CC line
when attached and both when unattached.
