net: stmmac: remove unnecessary "stmmac: wakeup enable" print

Printing "stmmac: wakeup enable" to the kernel log isn't useful - it
doesn't identify the adapter, and is effectively nothing more than a
debugging print. This information can be discovered by looking at
/sys/device.../power/wakeup as the device_set_wakeup_enable() call
updates this sysfs file.
