serial: sh-sci: Use platform_get_irq_optional() for optional interrupts
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.
