gpu: nvgpu: Move fuse override DT handling

Move fuse override DT handling to Linux code. All the chip specific
fuse override functions did the same thing, so delete the HAL and
call the same function to read the DT overrides on all chips.

Also remove the fuse override functionality from dGPU. There are no
DT entries for PCIe devices, so it would've failed anyway.
