On i.MX8M platforms the dram_apb and dram_alt are controlled from EL3. So in order to keep track of the actual clock tree in kernel, we need to actually declare the clocks but never actually change their parents or divider settings. We do that by marking the mux and the div as read-only with CLK_DIVIDER_READ_ONLY and CLK_MUX_READ_ONLY flags.
