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

[mark.cave-ayland at siriusit.co.uk]

From: Mark Cave-Ayland <mark.cave-ayland at siriusit.co.uk>

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.
