Subject: net: fec_ptp: Use platform_get_irq_xxx_optional() to avoid error
message
Patch-mainline: v5.4-rc6
Git-commit: b86bcb299092c1d5cd30f6188d58f73526ec9ada
References: bsc#1161695
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
