Modified PoE layout to account for GNDS-GND1 flow
and repositioned the noise retern capacitor.
Snubber was corrected for the transformer used and the switching
frequency. Some components were removed.
PoE Input filter was adjusted.
3.3 and 5V DCDC capacitor layout was optimised and unused components
were removed.
