Subject: net: fec_main: Use platform_get_irq_byname_optional() to avoid error
 message
Patch-mainline: v5.4-rc6
Git-commit: 3b56be218f65e26bb651095d7a5b107f67a6c5c2
References: bsc#1161695

Failed to get irq using name is NOT fatal as driver will use index
to get irq instead, use platform_get_irq_byname_optional() instead
of platform_get_irq_byname() to avoid below error message during
probe:

[    0.819312] fec 30be0000.ethernet: IRQ int0 not found
[    0.824433] fec 30be0000.ethernet: IRQ int1 not found
[    0.829539] fec 30be0000.ethernet: IRQ int2 not found
