bmc_booted LED group was not asserted when BMC started up

[vishwa]

Hi Stanley,

Could you tell:

-- The o/p of "systemctl status obmc-led-group-start at bmc_booted.service"

-- Properties of /xyz/openbmc_project/led/groups/bmc_booted

-- properties of xyz/openbmc_project/led/physical/heartbeat ?

!! Vishwa !!
