avrftdi_private.h, avrftdi.c: remove pdata->guard_bits refernces, since
they are no longer needed
avrftdi_tpi.c: Use fixed guard time of 2 bits, this gives 16 bits per
frame. tpi_byte2frame() and tpi_frame2byte() functions are now
symmetrical and extraction of received data in avrftdi_read_byte is less
complicted. Write the new guard time to the TPI in
avrftdi_tpi_program_enable().
