[PATCH 05/17] of: base: move clock init from of_probe() to barebox_register_of()

From: Marco Felsch <m.felsch at pengutronix.de>

This is required for the new deep-probe mechanism. Barebox deep-probe
calls of_probe() very late and so clock drivers using the old
CLK_OF_DECLARE_DRIVER() mechanism are added very late. This would break
the deep-probe approach.

Move of_clk_init() and call it right before of_probe() should have no
impact because of_clk_init() depends only on an unflatten dtb.
