clk: si5351: Do not pass struct clk in platform_data

Browse Source 
When registering clk-si5351 by platform_data, we should not pass struct clk
for the reference clocks. Drop struct clk from platform_data and rework the
driver to use devm_clk_get of named clock references.

While at it, check for at least one valid input clock and properly prepare/
enable valid reference clocks.
