Steve Baker 41f941a78e Fix GPIO pull up/down for Pi4B
Based on this raspi-gpio commit[1] the 2711 chip uses a different method
for pull up/down. This change implements that same method.

With this change, wiringPi now works for the Pi4B with the subset of
functionality used by zynthian.

wiringPi README
===============

Please note that the official way to get wiringPi is via git from
git.drogon.net and not GitHub.

ie.

  git clone git://git.drogon.net/wiringPi

The version of wiringPi held on GitHub by "Gadgetoid" is used to build the
wiringPython, Ruby, Perl, etc. wrappers for these other languages. This
version may lag the official Drogon release.  Pull requests may not be
accepted to Github....

Please see

  http://wiringpi.com/

for the official documentation, etc. and the best way to submit bug reports, etc.
is by sending an email to projects@drogon.net

Thanks!
