[PATCH platform-next v2 01/10] mellanox: Relocate mlx-platform driver

[Vadim Pasternak <vadimp@nvidia.com>]

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.

Add reference for Documentation/ABI/testing/sysfs-driver-mlxreg-io under
"MELLANOX HARDWARE PLATFORM SUPPORT".
