TCPMv2: Add support for disabling type-2 BIST mode
This CL adds a TCPCI method to disable BIST mode for the case where
the TCPC does not handle the duration automatically. This is required
for the ucpd driver as once type-2 BIST mode is started, the ucpd
peripheral needs to be reset to stop.
This CL also reduces the timer value from 60 msec to 55 msec to ensure
that there is enough time for BIST to be stopped and still be in spec.
BUG=b:182436876
BRANCH=None
TEST=verifed on Quiche that when type-2 BIST is started then it stops
when the timer in PE expires. This fixes TDA.2.1.1.1: BMC-PHY-TX-EYE
