clk: samsung: Modify _get_rate() helper to use __clk_lookup()
There is no need to use clkdev inside the clock driver to retrieve the clocks for internal use. Instead __clk_lookup() helper can be used to look up clocks by their platform name. This patch modifies the behavior of _get_rate() helper to look up clocks by platform name and adjusts all users of it to pass platform names instead of clkdev aliases.
