hdata: Detect LED mode and populate device tree
FSP based machine supports two different LED modes:
- Light Path : Both identify and fault LEDs are supported
- Guiding Light: Only identify LEDs are supported
And this information is passed to OPAL via HDAT. Lets parse this
and populate the device tree. Later LED driver uses this information
to populate indivisual LED node.
Device Tree property:
/ibm,opal/led/led-mode : lightpath/guidinglight
