sun4u: split out NPT and INT_DIS into separate CPUTimer fields
Currently there is confusion between use of these bits for the timer and timer
compare registers (while they both have the same value, the behaviour is
different). Split into two separate CPUTimer fields so we can always reference
the correct value.
