Paul Mackerras 8b1af56b29 powerpc: Fix i8259 cascade on pSeries with XICS interrupt controller ... It turns out that commit f9bd170a87 broke the cascade from XICS to i8259 on pSeries machines; specifically we ended up not ever doing the EOI on the XICS for the cascade. The result was that interrupts from the serial ports (and presumably any other devices using ISA interrupts) didn't get through. This fixes it and also simplifies the code, by doing the EOI on the XICS in the xics_get_irq routine after reading and acking the interrupt on the i8259.
