platform/x86: mlx-platform: Fix access mode for fan_dir attribute

Fix access mode for "fan_dir" attribute from "write only" to
"read only". This attribute is exposed to leds-mlxreg driver.
The purpose of this attribute is to provide information about FAN

It is relevant for the next generation systems MQMB7xx, MSN37xx,
MSN34xx, MSN38xx.
