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

	- The patch f1da567f1dc1 ("driver core: platform: Add platform_get_irq_byname_optional()")
	  already landed on network/master, resend this patch set.
