net: phy: mxl-gpy: correctly describe LED polarity

Browse Source 
According the datasheet covering the LED (0x1b) register:
0B Active High LEDx pin driven high when activated
1B Active Low LEDx pin driven low when activated

Make use of the now available 'active-high' property and correctly
reflect the polarity setting which was previously inverted.
