Some genpd providers doesn't ensure that it has turned off at hardware.
This is fine until the consumer really requires during some special
scenarios that the power domain collapse at hardware before it is
turned ON again.

An example is the reset sequence of Adreno GPU which requires that the
'gpucc cx gdsc' power domain should move to OFF state in hardware at
least once before turning in ON again to clear the internal state.

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.

There are unused clocks that need to remain untouched by clk_disable_unused,
and most likely could be disabled later on sync_state. So provide a generic
sync_state callback for the clock providers that register such clocks.
Then, use the same mechanism as clk_disable_unused from that generic
callback, but pass the device to make sure only the clocks belonging to
the current clock provider get disabled, if unused. Also, during the
default clk_disable_unused, if the driver that registered the clock has
the generic clk_sync_state_disable_unused callback set for sync_state,
skip disabling its clocks.
