firmware: arm_scmi: Drop config flag in clk_ops->rate_set
CLOCK_PROTOCOL_ATTRIBUTES provides attributes to indicate the maximum number of pending asynchronous clock rate changes supported by the platform. If it's non-zero, then we should be able to use asynchronous clock rate set for any clocks until the maximum limit is reached. In order to add that support, let's drop the config flag passed to clk_ops->rate_set and handle the asynchronous requests dynamically.
