Enable LED support for Romulus

Support for groups bmc_booted, power_on, enclosure_fault,
enclosure_identify, and lamp_test.

Allows lamp test to display all LED colors on a multi color LED
as part of the lamp test.

Notice there is no LED change for Power states.  That is because
the Romulus op panel does not run on standby power.  It is
impossible to do anything useful with the power LED.
