845dd0385eb738690ee19e60111952a363bbf257 hw/core/clock: allow clock_propagate on child clocks
clock_propagate() has an assert that clk->source is NULL, i.e. that
you are calling it on a clock which has no source clock. This made
sense in the original design where the only way for a clock's
frequency to change if it had a source clock was when that source
clock changed. However, we subsequently added multiplier/divider
support, but didn't look at what that meant for propagation.
If a clock-management device changes the multiplier or divider value
on a clock, it needs to propagate that change down to child clocks,
even if the clock has a source clock set. So the assertion is now
incorrect.
Remove the assertion.
