Subject: [PATCH RESEND 2/2] net: fec_ptp: Use platform_get_irq_xxx_optional() to avoid error message
Use platform_get_irq_byname_optional() and platform_get_irq_optional()
instead of platform_get_irq_byname() and platform_get_irq() for optional
IRQs to avoid below error message during probe:
[ 0.795803] fec 30be0000.ethernet: IRQ pps not found
[ 0.800787] fec 30be0000.ethernet: IRQ index 3 not found
