regulator: Fix suspend to idle
When suspending to idle with the new suspend mode configuration support
we go through the suspend callbacks with a state of PM_SUSPEND_TO_IDLE
which we don't have regulator constraints for, causing an error. Avoid
this and similar errors by treating missing constraints as a noop.
