[PATCH 1/1] dma: tegra: don't open code of_device_get_match_data()

[Laxman Dewangan]

Use of_device_get_match_data() for getting matched data
instead of implementing this locally.

I have applied this after fixing subsystem name. Please ensure you use the
right name

File names are also containing dma only and so this mistake happened.
Will keep in mind in future patches.
