From: Nishanth Menon <nm@xxxxxx>
clk_get does a check to find nodes on DT prior to trying clk_get_sys.
To make omap_device dt clock node aware, use clk_get instead of
clk_get_sys.
As part of this, add warnings for device node entries which do not
declare their own clock nodes for the expected aliases.
