hw/arm/aspeed_ast27x0: Avoid hardcoded '256' in IRQ calculation
When calculating the index into the GIC's GPIO array for per-CPU
interrupts, we have to start with the number of SPIs. 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.
