x86: GEODE: MFGPT: drop module owner usage from MFGPT API

We had planned to use the 'owner' field for allowing re-allocation of
MFGPTs; however, doing it by module owner name isn't flexible enough.  So,
drop this for now.  If it turns out that we need timers in modules, we'll
need to come up with a scheme that matches the write-once fields of the
MFGPTx_SETUP register, and drops ponies from the sky.
