The initialization order of SCU clocks affects the sequence of SCU clock
resume. If there are no other effects, the earlier the initialization,
the earlier the resume. During SCU clock resume, the clock rate is
restored. As SCFW guidelines, configure the parent clock rate before
configuring the child rate.

Fixes: 91e916771de0 ("clk: imx: scu: remove legacy scu clock binding support")
