sparc: writing to tick_cmpr should not cause a panic

This register is writable according to UA2005

Tried to boot NetBSD which starts the kernel by writing to the tick_cmpr
register.  Without the patch gem5 crashes with a panic.  With the patch NetBSD
starts to boot normally (although sun4v support in NetBSD is not complete yet)
