On FSP based machine, FSP controls System Attention Indicator. This
indicator detail (location code) is passed to OPAL via HDAT. OPAL
can get/set this indicator via normal MBOX command.
This patch takes care of parsing SLCA entry and populating device tree
with SAI location code.
Device Tree:
We create '/ibm,opal/led' node which contains all location code LED
information. 'led-types' property under each node tells LED type.
For SAI indicator 'led-types' property will be 'attention'.
