TCPMv2: Add common exit mode for all the alternate modes
When chipset is transitioning to a new state or on sysjump, the SOC
re-negotiates to enter an alternate mode on booting up.
This commit:
1. Adds a common DPM function to check for all the active alternate modes
one at a time, construct the VDM and send the DPM request to exit the
mode.
2. Marks thunderbolt mode as inactive in DFP's thunderbolt mode exit
function.
BUG=b:152235216
BRANCH=None
TEST=Tested on volteer:
1. On connecting a DP dongle, able to enter into DP alternate mode
on reboot
2. On connecting a Thunderbolt dock, able to enter into Thunderbolt
mode on reboot
