mb/pcengines/apu2: Update GPIO Reads & writes

The APU2 was using the soc/amd/common functions to do GPIO reads and
writes.  The functions that were being used are getting eliminated in
the SOC directory, but since the APU isn't using the rest of that code
(as it's not using the rest of the SOC codebase), it proved to be
problematic to use the updated functions.

The solution I've put in place here is to pull everything needed for the
GPIO reads & writes into the gpio_ftns.c & h files.
