Are all the PSCI 0.2 mandatory features implemented?

The system off/suspend is under development, and system off will
be released in next months, and system suspend may be released in the
following two months.

Yes; now for mandatory features, except SYSTEM_OFF others have supported.
for PSCI 0.2, SYSTEM_SUSPEND even is not supported, right?

So can I keep "arm,psci-0.2" here?

Can CPU0 be hot unplugged?

Yes, CPU0~CPU7 all can be hot unplugged.

Just clarify: now use s/w method to emulate CPU and cluster's low
power state; all cores can be hotplugged [1].
