tty: serial: imx: Use platform_get_irq_optional() for optional IRQs
All i.MX SoCs except i.MX1 have ONLY one necessary IRQ, use
platform_get_irq_optional() to get second/third IRQ which are
optional to avoid below error message during probe:
[ 0.726219] imx-uart 30860000.serial: IRQ index 1 not found
[ 0.731329] imx-uart 30860000.serial: IRQ index 2 not found
Fixes: 7723f4c5ecdb8d83 ("driver core: platform: Add an error message to platform_get_irq*()")
