tcpmv2: perform partner reset on startup, remove BBRAM
- Reset the port partner by applying CC Open on both CC lines
- Reuse the existing error recovery state to apply CC values
- Extend error recovery timer to 240 msec to account for us being able
to source Vconn
- Since we always reset on startup, we don't need to store previous
contracts in BBRAM.
BRANCH=none
BUG=b:159495742,b:158802939
TEST=see that we apply CC Open upon reset
TEST=see that we do not get a fault on Trembyle went setting CC open
TEST=apple 3-1 dongle with display port and power on Puff will come back
with power and display after a `reboot` EC command (which will trigger
the ErrorRecovery brownout path)
