Subject: [PATCH net-next] net: phy: qca807x: Drop unnecessary and broken DT validation

The check for "leds" and "gpio-controller" both being present is never
true because "leds" is a node, not a property. This could be fixed
with a check for child node, but there's really no need for the kernel
to validate a DT. Just continue ignoring the LEDs if GPIOs are present.
