acer-wmi: Mark init data and code as such 



Quite a lot of code and data of acer-wmi.c is only ever used during
initialization. Mark those accordingly -- and constify, where
appropriate -- so the memory can be released afterwards.

All in all those changes move ~10 kB of code and data to the .init
sections, marking them for release after initialization has finished.
