[SPARC64]: Fix Tomatillo/Schizo IRQ handling.

The code in schizo_irq_trans_init() should set irq_data->sync_reg
to the location of the SYNC register if this is Tomatillo, and set
it to zero otherwise.  But that is not what it is doing.

As a result, non-Tomatillo systems were trying to access a
non-existent register resulting in bus errors at the first
PCI interrupt.

Thanks to Roland Stigge for the bug report.
