The clk_enable is supposed work when CONFIG_HAVE_CLK is false, but it
returns -EINVAL. That means some drivers fail during probe.
[ 1.680000] flexcan: probe of flexcan.0 failed with error -22
Fixes: c1fb1bf64bb6 ("m68k: let clk_enable() return immediately if clk is NULL")
Fixes: bea8bcb12da0 ("m68knommu: Add support for the Coldfire m5441x.")
