In what conditions pmu_data will be NULL?

What if we want driver to be probed but no data has been given?
If driver gets probed it still can act as syscon provider, and other IPs can
access
PMU registers, but PMU functionality itself will not be available, for same
reason
I have put a check for pmu_data in powerdown_conf also.

Is there any point in probing this driver just to register the syscon?
AFAIK if this driver errors out, the syscon platform driver will take
over and do what we want. That's why we have the second "syscon"
compatible string.
