tcpm: anx74xx: Remove auto-toggle support
Auto-role toggle on the anx74xx does not function correctly with
e-marked cables and cannot be used.
Also check for TCPC support for auto-toggle at runtime, to allow
auto-toggle supported TCPC to be used alongside an unsupported part.

BUG=chrome-os-partner:60890
BRANCH=reef
TEST=Manual on reef, boot to S0:
`pd 0 state`: Toggling between SRC_DISCONNECTED / SNK_DISCONNECTED
`pd 1 state`: DRP_AUTO_TOGGLE
Also verify port 0 can become sink + source correctly in S0.
