Added support for Power-Down pin on ATF16V8C 

The PD feature is now selectively enabled or disabled based
on the JED contents. Also, when fuses are read the printout
of the JED file reflects the PD fuse bit state. So, when
the PD fuse bit is enabled then the JED file contains an extra
fuse bit set to 1. The ATF22V10C now behaves the same way regarding
the PD fuse bit (previously Afterburner always disabled the PD
function).
