dmaengine: tegra210-adma: Update driver to use of_pm_clk_add_clk
Commit 498b5fdd40dd ("PM / clk: Add support for adding a specific clock from device-tree") add a new helper function for adding a clock from device-tree to a device. Update the ADMA driver to use this new function to simplify the driver.
