[POWERPC] cell/PS3: Fix a bug that causes the PS3 to hang on the SPU Class 0 interrupt.
The Cell BE Architecture spec states that the SPU MFC Class 0 interrupt is edge-triggered. The current spu interrupt handler assumes this behavior and does not clear the interrupt status. The PS3 hypervisor visualizes all SPU interrupts as level, and on return from the interrupt handler the hypervisor will deliver a new virtual interrupt for any unmasked interrupts which for which the status has not been cleared. This fix clears the interrupt status in the interrupt handler.
