clk: imx8mm: Mark dram_apb critical 



This clock is used for dram operations inside TF-A and must be kept
enabled for features such as suspend/resume dram retention and busfreq
to work.

This is required for imx8mm suspend to work with NXP branch of TF-A.
There is an equivalent clk on imx8mq and it's always been marked as
critical in upstream.
