Subject: [PATCH v4 2/3] clk: s2mps11: Remove useless check for clk_table

There is no need for checking if 'clk_table' is not NULL twice (first
after allocation and second at the end of probe()). Also move allocation
of this 'clk_table' to probe from s2mps11_clk_parse_dt as this is
logical place for it.
