The member "data" of structure of_device_id is changed to const
pointer. Hence initializing this with const type data.
This will fix the compilation warning like
drivers/dma/tegra20-apb-dma.c:1217:9: warning: assignment discards 'const' qualifier from
pointer target type [enabled by default]
This warning came after the change
