platform/x86: mlx-platform: Move module from arch/x86
Since mlx-platform is not an architectural driver, it is moved out of arch/x86/platform to drivers/platform/x86. Relevant Makefile and Kconfig are updated. Signed-off-by: Vadim Pasternak <vadimp@mellanox.com> Acked-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
