Debarshi Dutta 028b6dd811 gpu: nvgpu: update dma_mask based on H/W compatibility
To be able to access the full physical memory range, gpu's dma_mask
needs to be set to the max value of H/W compatible range.

For example. In order to support from 2GB to 66 GB, GV11B's dma_mask
needs to be atleast 37 bits. Set GV11B's dma_mask to 38 bit
and T23X's dma_mask to 39 bit. These values are supported by H/W.
