By adding the newly added clk_sync_state_disable_unused as sync_state callback to all sdm845 clock providers, we make sure that no clock belonging to these providers gets disabled on clk_disable_unused, but rather they are disabled on sync_state, when it is safe, since all the consumers build as modules have their chance of enabling their own clocks.
