Just for curiosity, we had similar situation on imx6sx, so we added suspend/resume with regcache. Why will the clock enable state be lost too? Does CCM on imx8 (might not be called CCM though) have any difference? What about clock rate settings?
That sounds like a bug somewhere else - I'd expect that after resume the clocking would be restored to the state it was in before suspend.
