[PATCH] Fix level 14 and level 10 timers under Solaris 8 on SPARC32.

From: Mark Cave-Ayland <[e-mail]>

During boot, if the level 14 timer limit is not set then the Solaris kernel panics with a division by zero
error. Fix this by setting it to the default value as documented in obio.h. Also if the level 10 timer is
not set with a limit of 0, the Solaris kernel constantly outputs "spurious interrupt at processor level
10" messages during boot.

Okay great - looks fine with my test images too, so will commit shortly.
