gpu: nvgpu: nvlink: Add HAL to get link_mask

VBIOS link_disable_mask should be sufficient to find the connected
links. As VBIOS is not updated with correct mask, we parse the DT
node where we hardcode the link_id. DT method is not scalable as same
DT node is used for different dGPUs connected over PCIE. Remove the
DT parsing of link id and use HAL to get link_mask based on the GPU.
