tm6000 locking fixes

There are a number of locking issues at tm6000 driver.

This series fixes those locking issues. After them, both mplayer and tvtime are not causing panic/oops, even if I call it via a remote machine.

Unfortunately, my HVR-900H died (probably due to overheat), so I can't test anymore the tm6010 alsa fixes, but, on the tests I did with tm6000, the start/stop of audio is not causing OOPS/Panic anymore (yet, some extra init is needed for tm6000 to have audio).
