TCPMv2: Don't exit DP mode on chipset suspend and resume

A PD_EVENT_POWER_STATE_CHANGE event was generated on a
chipset suspend/resume. If DP mode was active, the
PD_EVENT_POWER_STATE_CHANGE event would cause the
DP mode to exit. To prevent this, the event will
not be generated on chipset suspend/resume.

BUG=b:147265554
BRANCH=none
TEST=make -j buildall
	manual: Connected DP to chromebook and verified
		DP mode was not exited on chipset
		suspend nd resume.
