hw/arm/highbank: Specify explicitly the GIC has 128 external IRQs
When not specified, Cortex-A9MP configures its GIC with 64 external IRQs, (see commit a32134aad89 "arm:make the number of GIC interrupts configurable"), and Cortex-15MP to 128 (see commit 528622421eb "hw/cpu/a15mpcore: Correct default value for num-irq"). The Caldexa Highbank board however expects a fixed set of 128 interrupts (see the fixed IRQ length when this board was added in commit 2488514cef2 ("arm: SoC model for Calxeda Highbank"). Add the GIC_EXT_IRQS definition (with a comment) to make that explicit. Except explicitly setting a property value to its same implicit value, there is no logical change intended.
