tcpmv2: disable receive of SOP' during VCONN swap
The USB PD specification indicates that the initial VCONN source shall
cease source VCONN within tVCONNSourceOff (25 ms) after receiving
PS_RDY. Not all partners wait after sending PS_RDY before trying to
communicate with the cable.
BUG=b:163478172, b:163143427
BRANCH=none
TEST=make buildall
TEST=Connect 2 Volteers together and force VCONN swaps confirming the
sequence completes normally.
