This adds a BASIC touch support to the verilog blink example

[LeonFedotov]

I wonder if theres a better way to use touch in verilog, i was told that those pads on the pvt version are connected straight to the fpga but in the schematic i see diodes as well. any input? thanks! :)

@LeonFedotov This looks good - did you mean to close it?

@LeonFedotov -- if you want extra Fomus, I'm happy to give you some for doing this...

[LeonFedotov]

@mithro yea hi, reason i closed it is that i saw blink-minimal example already attempts to have the same behavior and im not sure which way is the correct one ☝️ I would like to learn verilog with the fomu but the docs and the examples are a little patchy for me... i would love to help out with that...

@mithro i would love for some more, are you still at the congress? Cc: @corecode

I guess this should go in a separate example.

I think that this is a good candidate for a different example.

Incidentally, I have a captouch driver (as opposed to this resistive driver) done at https://github.com/xobs/fomu-captouchtest/blob/master/rtl/fomucaptouch.py
