patch #5096: Allow VCC and BUFF to be any pin in parallel mode

* config_gram.y: Release the restriction to PPIDATA pins.
* par.c: Rework the code to introduce a function par_setmany()
that builds on top of par_setpin(), and use that function for the
PPI_AVR_VCC and PPI_AVR_BUFF pin collections.  This also abstracts
the polarity of these signals appropriately.
