intelblocks/pep: Send All Monitor Off/On command only in FWCM case
ALL_MONITOR_OFF command is sent using DPOF.
TBT controller needs to be notified about ALL_MONITOR_OFF(TBT Displays OFF) only when Firmware Connection Manager(FWCM) is in use during S0ix Entry/Exit. When configured for SWCM this command should not be sent.
BUG=b:288536417
TEST= Build and boot Rex Proto-1. Verify S0ix working.
