According to the current imx_clk_sccg_pll design, it uses both

When setting the 100MHz, 500MHz, 666MHz and 1GHz rate for CPU clocks,
CCF will use the SYS_PLL to handle these frequencies, but:
- using FIXED_PLL derived FCLK_DIV2/DIV3 clocks is more precise
- the Amlogic G12A/G12B/SM1 Suspend handling in firmware doesn't
  handle entering suspend using SYS_PLL for these frequencies

Adding CLK_MUX_ROUND_CLOSEST on all the muxes of the non-SYS_PLL
cpu clock tree helps CCF always selecting the FCLK_DIV2/DIV3 as source
for these frequencies.
