[PATCH 2/4] hwrng: omap - use devm_clk_get() instead of of_clk_get()

[Thomas Petazzoni]

The omap-rng driver currently uses of_clk_get() to get a reference to
the clock, but never releases that reference. This commit fixes that by
using devm_clk_get() instead.

Fixes: 383212425c926 ("hwrng: omap - Add device variant for SafeXcel IP-76 
found in Armada 8K")
