* 3. In the RTL implementation of the LDB_DI_CLK_SEL mux
* the top four options are in one mux and the PLL3 option along
* with another option is in the second mux. There is third mux

* The code below switches the parent to the bottom mux first
* and then manipulates the top mux. This ensures that no glitch
* will enter the divider.
*
* Need to disable MMDC_CH1 clock manually as there is no CG bit
* for this clock. The only way to disable this clock is to move
* it topll3_sw_clk and then to disable pll3_sw_clk
