PM / clk: Do not __clk_get passed in clock-references

Commit-Message
Clock references are on a per-user basis now, so they are not supposed to be refcounted by itself anymore. Therefore multiple cascaded get and put calls will fail. When a clock reference gets passed into pm_clk_add_clk we can assume that the pm clock handling will take control of the clock reference, so after this functions returns the caller should've given up control of that handle. So remove the additional call to __clk_get() in __pm_clk_add(). The only current user of pm_clk_add_clk is drivers/clk/shmobile/clk-mstp.c which already follows this paradigm by only getting the clock but not puting it after passing the reference into pm_clk_add_clk. In the error case the caller is expected to clean up the clock, as it may very well try to do something different if pm_clk_add_clk() fails.
