platform/x86: mlx-platform: Add LED platform driver activation
Add LED platform driver activation from mlx-platform. This LED driver uses the same regmap infrastructure as others Mellanox platform drivers, so LED specific registers description is added. System LED configuration depends on system type. To support all the relevant types per system type LED descriptions are defined for passing to LED platform driver.
