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.
