PICkit 2 again with HPS stack

[Xiaofan Chen]

I have updated the kernel and the new HPD stack and now
PICkit 2 is again not working. I have updated the firmware
based on the newly released Microchip stack and I thought
I solved the data toggle problem by changing a line as
suggested by Leo Bodnar.

Apparent there is still a problem with the clear feature
request. Enclosed is the running log. Since the file ugen.c
is now changed, I dare not to apply the old patches provided
by Hans.
