> As platform_get_irq() now prints an error when the interrupt does not
> exist, scary warnings may be printed for optional interrupts:
>
> sh-sci e6550000.serial: IRQ index 1 not found
> sh-sci e6550000.serial: IRQ index 2 not found
> sh-sci e6550000.serial: IRQ index 3 not found
> sh-sci e6550000.serial: IRQ index 4 not found
> sh-sci e6550000.serial: IRQ index 5 not found
>
> Fix this by calling platform_get_irq_optional() instead for all but the
> first interrupts, which are optional.
