Place EC data to configuration files

[ThisIsRex]

It seems to be a good idea to place the EC addresses, firmware versions, etc into the config files. This is a good idea because you can add new firmware versions without rebuilding the driver. Also, I don't know the C language, I've never written in it but know addresses and values for my laptop and can add them. What do you think?

This wouldn't work for a kernel module. Also, adding the configs in runtime without rebuilding the module doesn't really have a usecase for this driver.

The only thing I see being useful is moving the configs to a separate source code file to take the load off of the main msi-ec.c file.
