avrftdi: add pgm->power[up|down], fix pgm->enable|disable 

avrftdi.c: add pgm->power[up|down] functions and fill
pgm->enable|disable with proper functionality, as suggested by
rliebscher.

* avrftdi_private.h: Change size of pin_checklist to N_PINS (from N_PINS-1)
* avrftdi.c: Adapt code to new size of pin_checklist. Remove pins_check()
from set_pin().
Add pgm->power[up|down] functions as well as fill pgm->enable|disable with
proper content as suggested by Rene Liebscher.
