Enabling the clk drivers on msm8994 allows to boot and test most device
drivers on this SoC.

Thanks for your tip. Sure, if it's safe to change the rest of CONFIG_MSM_MMCC_.*
to module as well (in separate patch). I'll send v2.

Probe defer support has been there for a long time, but it was not
reliable after late_initcall.

I believe 2b28a1a84a0e ("driver core: Extend deferred probe timeout on
driver registration") is the change that altered the behavior, so we can
now use it for kernel modules as well.

Thanks for info! I have v2 prepared, but I'd prefer to test it, thus I'll send
it next week after I get time to test it.
