TBT:Add support for exit mode SOP'/SOP'' on chipset transition
When chipset is transitioning to a new state or on sysjump, the EC
re-negotiates to enter an alternate mode on booting up.
This commit adds support for exiting Thunderbolt mode for SOP' and SOP''
for active cable on chipset transition and also moves all the alternate
mode exit rotines to their respective files.
It also delays deleting the SVID data until after the EXIT_MODE message
has ACKed and avoids pd_dfp_exit_mode() from changing the alternate
mode's internal states.
This commit also makes sure that the mux is set to safe state before
exiting the alternate mode and it is reconfigured according to the
port's current data role on receiving ACK/NAK from the cable/port
partner.
BUG=b:151169925, b:159717794
BRANCH=none
TEST=On reboot, able to exit and re-enter into DisplayPort mode,
Thunderbolt mode with passive cable and thunderbolt mode with
active cable.
