FSP/LEDS: Add support to handle SAI state request from service processor
Ideally service processor shouldn't request OPAL for SAI state...as this
LED is controlled by service processor itself.
But of some reason its asking OPAL to provide state. Hence handle this
request until FSP team fixes it.
Sample log without this patch:
[77884350335,3] FSPLED: Could not find the location code LC=U8246.L2C.060377A
[77942662287,8] FSPLED: FSP_CMD_GET_LED_LIST command received
