makes it a little easier to notice that parity checking an 8bit sram isn't working. Turn on scb and internal data-path parity checking for all pci chips types. We were only doing this for ultra2 chips. After clearing the parity interrupt status, clear the BRKADRINT. This avoids seeing a bogus BRKADRINT interrupt after external SCB probing once normal interrupts are enabled.
