hw/cpu/a15mpcore: Correct default value for num-irq
The a15mpcore device claims that its default value for num-irq is the number of interrupts used by the A15MP in the vexpress-a15 board. However that chip has 128 external interrupts, not 64. Since there is only one A15 based model in QEMU currently, we can fix this by simply changing the default value. This error was causing recent (3.10) Linux kernels to print warnings/backtraces when the number of interrupts reported by the GIC was smaller than an interrupt number they wanted to use.
