Prevent from erasing the pinmux of HW ephy LEDs in BCM6368
In BCM6368 CFE configures the HW controled LEDs for the switch
by setting the required GPIO pinmux. But in OpenWrt when the
peripherals are initialized, the code is erasing the pinmux previously
configured by CFE.
Just don't erase those bits to let the LEDs blink with LAN activity.
