some time ago I submitted a similar patch for the 32-bit SoCs
it turned that that pwm-meson can be built as module because the
kernel will run without CPU DVFS as long as the clock and regulator
drivers are returning -EPROBE_DEFER (-517)
did you check whether there's some other problem like some unused
clock which is being disabled at that moment?
I've been hunting weird problems in the past where it turned out that
changing kernel config bits changed the boot timing - that masked the
original problem
