bnx2x: Move all UDP port notifiers to single function

Browse Source 
This patch goes through and combines the notifiers for VXLAN and GENEVE
into a single function for each action.  So there is now one combined
function for getting ports, one for adding the ports, and one for deleting
the ports.

I also went through and dropped the BNX2X VXLAN and GENEVE specific build
flags.

This enables hardward offload support for VXLAN protocol over the

This allows one to create GENEVE virtual interfaces that provide
Layer 2 Networks over Layer 3 Networks. GENEVE is often used
to tunnel virtual network infrastructure in virtualized environments.
