From: Matthias Schiffer <matthias.schiffer@xxxxxxxxxxxxxxx>
of_clk_add_provider() may be called for devices added via
add_generic_device(). There is no OF node in this case, leading to a crash
when debug logs are enabled.
This affects various i.MX CPUs, which add imx*-ccm clock devices using
add_generic_device().
