The code currently hard-codes this to 'NUM_IRQS = 256'. However the number of SPIs is set separately and implicitly by the value of AST2700_MAX_IRQ, which is the number of SPIs plus 32 (since it is what we set the GIC num-irq property to). Define AST2700_MAX_IRQ as the total number of SPIs; this brings AST2700 into line with AST2600, which defines AST2600_MAX_IRQ as the number of SPIs not including the 32 internal interrupts. We can then use AST2700_MAX_IRQ instead of the hardcoded 256.
