clk: qcom: Allocate space for NULL terimation in DFS table
The table allocated in clk_rcg2_dfs_populate_freq_table() is
eventually iterated over by qcom_find_freq() which assumes that the
table is NULL terminated. Allocate one extra space in the array for
the NULL termination. Initting of the NULL termination is implicit
due to kcalloc().
Fixes: cc4f6944d0e3 ("clk: qcom: Add support for RCG to register for DFS")
