[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.
