clk: imx93: add MU1/2 clock
The clk tree should be as:
bus_aon_root------>\ /--->MU1_B IP
-->MU_B gate-->
bus_wakeup_root--->/ \--->MU2_B IP
bus_aon_root------>\ /--->MU1_A IP
-->MU_A gate-->
bus_wakeup_root--->/ \--->MU2_A IP
So need use shared count gate. And linux use MU_B,
so set MU_A clk as CLK_IGNORE_UNUSED.
