mmc: sdhci: tegra: Add setting for dma-mask

Currently, there is no binding for coherent_dma_mask and dma_mask
in device tree. If sdhci-tegra driver is probed from DT,
coherent_dma_mask will be set to 32 bit as DT default and
dma_mask will be NULL.
So added coherent_dma_mask setting for each Tegra SKUs.
And if dma_mask is NULL, set it to coherent_dma_mask.
