Subject: [PATCH v1] clk: qcom: Add support for RCG to register for DFS

 [v1]
   * Update SPDX for files.
   * Add new clk_ops for DFS mode which would be used if dfs is enabled,
     else fall back to the clk_rcg2_shared_ops.
   * Use kcalloc in place kzalloc.
   * Fixed the return type for 'clk_parent_index_pre_div_and_mode' which
     is now renamed to 'clk_index_pre_div_and_mode'.
   * Removed return of -EPERM from 'clk_rcg2_set_rate' and new dfs
     clk_ops is introduced.
   * Pass frequency table entry structure to function calculate_m_and_n.
   * Remove desc from qcom_cc_register_rcg_dfs and instead pass array of
     clk_rcg2.
   * Add a dfs_enable flag to identify if dfs mode is enabled.

In the cases where a RCG requires a Dynamic Frequency switch support
requires to register which would at runtime read the clock perf level
registers to identify the frequencies supported and update the frequency
table accordingly.
