FSP/LED: Add system attention indicator support
SAI is controlled by FSP. This patch adds support to get/set
this indicator. Also update OPAL interface so that playload
can read/set this indicator.
During init, we read this indicator state using MBOX command.
OPAL uses MBOX interface to update this SAI.
FSP sends update notification whenever there is change in SAI
state (except for OPAL initiates updates). We use the notification
to update cached SAI state.
