ppc/xive2: Implement "Ack OS IRQ to even report line" TIMA op
Booting AIX in a PowerVM partition requires the use of the "Acknowledge O/S Interrupt to even O/S reporting line" special operation provided by the IBM XIVE interrupt controller. This operation is invoked by writing a byte (data is irrelevant) to offset 0xC10 of the Thread Interrupt Management Area (TIMA). It can be used by software to notify the XIVE logic that the interrupt was received.
