Split this up into 2 seperate patches;
- Generify driver i.e. rk808 => rk8xx
- Add support for RK818

It is not possible for this to be NULL. No need for the check.

Is there no way to fetch this from the device, i.e. though a register
read?

It wasn't "found". The device hasn't been probed. You are assuming
this device is connected because that's what the DT says. Only print
these types of dev_info() prints when you have actually talked to the
device and confirmed it's presence.
