mei: expose fw version to sysfs
The ME FW version is constantly used by detection and update tools. To improve the reliability and simplify these tools provide a sysfs interface to access version of the platform ME firmware in the following format: <platform>:<major>.<minor>.<milestone>.<build>. There can be up to three such blocks for different FW components.
