Remove 0017; MAX9295 GPIO tunneling consolidated into 0016
Rename GPIO tunneling patches to include 'max9295' in filename. Consolidate GPIO tunneling register config from separate max9295 patch into the max96712 support patch. Update max96712 patches with ESYNC GPIO tunneling support across all JetPack versions (5.0.2, 5.1.2, 6.0, 6.1, 6.2, 6.2.1, 7.0, 7.1).
