Whilst trying to boot FreeBSD SPARC64, it became apparent that the existing
timer code doesn't behave correctly with respect to the NPT and INT_DIS
bits. This patchset corrects this behaviour and allows FreeBSD SPARC64 boot
to progress further.
Many thanks to Marius Strobl <mar...@alchemy.franken.de> for pointing me in
the right direction.

sun4u: split out NPT and INT_DIS into separate CPUTimer fields
sun4u: split NPT and INT_DIS accesses between timer and compare
registers
target-sparc: implement NPT timer bit
