adrv9009/adrv9371x/fmcomms2:Drop usage of ad_iobuf on non-bidirectional IOs 

Some projects use the ad_iobuf on IOs that are not bidirectional
producing synthesis warnings.

The change fixes warnings like:
[Synth 8-6104] Input port 'gpio_bd_i' has an internal driver
[Synth 8-6104] Input port 'gpio_status' has an internal driver
