dmaengine: tegra210-adma: Update driver to use of_pm_clk_add_clk

Browse Source 
Commit 498b5fdd40 ("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.
