[PATCH stable 6.1] phy: phy-brcm-usb: Utilize platform_get_irq_byname_optional()

[Florian Fainelli]

commit 53bffe0055741440a6c91abb80bad1c62ea443e3 upstream

The wake-up interrupt lines are entirely optional, avoid printing
messages that interrupts were not found by switching to the _optional
variant.
