clk: qcom: Add sync-state callback for clk-aop-qmp

Add sync-state callback for the clk-aop-qmp driver to ensure its clocks
don't turn off before all consumers probe. This also addresses
performance issues during boot since a large number of amba devices
toggle the QDSS clock in their probe function. Keeping the clock enabled
until all consumers probe means we don't make multiple expensive
round-trips to AOP.
