dmaengine: tegra: Use struct for register offsets

Browse source

Repurpose the struct tegra_dma_channel_regs to define offsets for all the
channel registers. Previously, the struct only held the register values
for each transfer and was wrapped within tegra_dma_sg_req. Move the
values directly into tegra_dma_sg_req and use channel_regs for
storing the register offsets. Update all register reads/writes to use
the struct channel_regs. This prepares for the register offset change
in Tegra264.
