msm: clock: Decrease voltage voting overhead for RPM and PCOM clocks The clk_get_rate() calls that were added to clk_enable(), clk_disable(), and clk_set_rate() to support voltage scaling result in unnecessary round-trips to the remote processor for remotely-managed clocks. Fix this by caching the last set rate in 'struct clk' instead of calling clk_get() to query it.
