Modified Files:
        src/sys/arch/macppc/dev: lmu.c

Log Message:
make this work properly:
- get rid of cargo-culted register assignments, I found the right ones by
  experiment, now both light sensors report sane values
- keyboard brightness seems to max out at 16, act like it
- do what MacOS does and fade keyboard brightness instead of just switching
- add sysctls to configure keyboard brightness and environmental light
  thresholds
- don't poll the chip more often than once a second
