This timer frequency is a half of the CPU frequency. To get clocks properly set we need to call to 'of_clk_init()' and properly get cpu clock frequency afterwards. Depending on the SoC, CPU clock index and compatible differs, so use them to get the proper clock frm the clock provider. Hence, adapt code to be aligned with new clock driver.
