EDAC/synopsys: Use the correct register to disable the error interrupt on v3 hw
commit be76ceaf03bc04e74be5e28f608316b73c2b04ad upstream.
v3.x Synopsys EDAC DDR doesn't have the QOS Interrupt register. Use the
ECC Clear Register to disable the error interrupts instead.
Fixes: f7824ded4149 ("EDAC/synopsys: Add support for version 3 of the Synopsys EDAC DDR")
