[RFC 01/19] clk: imx8mq: Replace critical with ignore_unused flag for dram_apb clock

In order to allow the dram_apb to be switched to a different parent,
we need to remove the CLK_IS_CRITICAL flag. This leads to clock
being disabled on clk_disabled_unused call, so add the
CLK_IGNORE_UNUSED instead to avoid that.
