[PATCH 4/4] commands: of_overlay: Allow to register clocks from overlay

[Sascha Hauer <s.hauer@pengutronix.de>]

When clocks are added from an overlay calling of_probe() is enough
for devices handled by regular drivers, but not for clocks declared
with CLK_OF_DECLARE(). Additionally call of_clk_init() to support
these as well.
