Subject: [PATCH V3 net-next 1/7] net: bcmgenet: Avoid touching non-existent interrupt

As platform_get_irq() now prints an error when the interrupt does not
exist, we are getting a confusing error message in case the optional
WOL IRQ is not defined:

  bcmgenet fd58000.ethernet: IRQ index 2 not found

Fix this by using the platform_get_irq_optional().

Fixes: 7723f4c5ecdb8d83 ("driver core: platform: Add an error message to platform_get_irq*()")
