Move 'mlx-platform' driver 'x86' to 'mellanox' folder.
Motivation to allow running it on systems with ARM architecture.
Since drivers/platform/x86/mlx-platform.c is rellocated to folder
drivers/platform/x86/, remove "MELLANOX PLATFORM DRIVER" item.
This driver will be located under "MELLANOX HARDWARE PLATFORM SUPPORT"
item.
