MLK-17491-46 clk: imx7ulp: add missing sosc_bus_clk/firc_bus_clk/spll_bus_clk clocks
Add missing sosc_bus_clk/firc_bus_clk/spll_bus_clk clocks which will be used
by other devices later.
All these clocks use the same divider as ddr_div, so ulp_div_table is used.
Besides that, all these clocks need to be controlled by M4, so
CLK_DIVIDER_READ_ONLY is also specified.
Fixes: aacf0b70af26 ("MLK-13441-6 ARM: imx: add i.mx7ulp clock driver")
