system_top: Non functional changes in system_tops to reduce warnings

Loop back the unused GPIO pins, and add all the SPI interface to system
wrapper instance.

The following system_top modules were changed:
  - ad738x_fmc
  - ad7616_sdz
  - ad77681evb
  - ad77681evb
  - ad7768evb
  - ad9739a_fmc
  - ad9434
  - adrv9739
  - fmcadc5
  - ad6676evb
  - ad9265
  - ad5766
  - fmcomms5
  - m2k
