ANDROID: GKI: clk: Add support for clock providers with sync state

Clock providers whose drivers have sync_state() implemented will disable
their clocks once all their consumers have probed. So during
late_initcall_sync(), don't disable unused clocks of these clock
providers.

Also, provide a clk_sync_state() API that clock providers can use to
disable all their unused clocks once they get their sync_state()
callback.
