[PATCH 7/8] platform/x86: int3472: Support LED lookups in board data

[Daniel Scally <dan.scally@ideasonboard.com>]

On platforms with the TPS68470 PMIC, we need to be able to define
which of the LEDs powered by the PMIC should be used by each of
the sensors that consume its resources. Add the ability to define
tables of LED lookup data to the board data file.
