dma: tegra: use sg_dma_address() for getting dma buffer address

Browse source 
Use the sg_dma_address() to get the segment buffer address for
DMA transfer in place of sg_phys() which returns the physical
address of an sg entry.
The sg_dma_address() returns the correct buffer memory address
for DMA transfer.
