Hi,

this patch allow to choose the behavior of the pnpacpi driver, it could 
  don't lock the acpi device like in mm5 or it could lock it like in mm2.

I have add extra check (CRS presence), so it shouldn't lock too much 
driver like in mm2.
I also add the hpet id in the blacklist, because we need to do an pnp 
driver for it.

Battery, Button and Fan may be remove from the blacklist because they 
don't seem to have CRS.

Please review it and apply if possible

thanks,

Matthieu CASTET
