From: Geert Uytterhoeven <geert+renesas@xxxxxxxxx>
clk_get() on a disabled clock node will return -EPROBE_DEFER, which can
cause drivers to be deferred forever if such clocks are referenced in
their devices' clocks properties.
Update the various disabled external clock nodes to default to a
frequency of 0, but don't disable them, to prevent this.
