Subject: [PATCH 2/2] clk: qcom: sdm845: Use generic clk_sync_state_disable_unused callback

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 had their chance of enabling
their own clocks.
