* Need to follow a strict procedure when changing the LDB

* mind:
* 1. The current and new parent clocks must be disabled.
* 2. The default clock for ldb_dio_clk is mmdc_ch1 which has
* no CG bit.
* 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
* used to decide between the first and second 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 to pll3_sw_clk and then to disable pll3_sw_clk
* Make sure periph2_clk2_sel is set to pll3_sw_clk
