Nate Lawson 4f8c4e4d53 Update a quirk for the ASUS P5A to disable the timer. It appears to work fine 
with acpi but the timer runs twice as fast.  Note that the main problem
(system doesn't work properly with acpi disabled) should be fixed separately.

Changes:
* Add a quirk to disable the timer
* Merge the P5A and P5A-B quirks since they appear to be based on the
  same ASL.
