Adjust PoE and change 3.3V supply topology

Browse Source 
-Snubber circuit under ecrtail load condition can dissipate more power
then the resistor can handle, increased the resistor size and added one
more in parallel
-Increased size of some of the 12V input capacitors
-Use 3.3Vp instead of 3.3V generated by the RPi for LED, RTC, Radio, Fan
control and RPi reduced hat connector
-PoE pri/sec capacitor value changed
