  Well, that wasn't as tricky as I thought. First observation was that
trying to run a Plus image on a Pro was not the way to go -- got these
boot errors after which the boot hung:

[   12.397294] fan53555-regulator 1-0042: FAN53555 Option[0] Rev[0] Detected!
[   12.397957] fan53555-regulator 1-0042: Chip ID 0 not supported!
[   12.398511] fan53555-regulator 1-0042: error -EINVAL: Failed to setup device!
[   12.399372] fan53555-regulator 1-0042: probe with driver fan53555-regulator failed with error -22

so based on some online pointers, I defined a "generic" Orange Pi 5
machine (for which all the underlying RK3588S content was already
mostly there), built for that new machine, and got a successful boot.
Just means I'm not including any Pro-specific features (yet), but all
I wanted was a bootable image.
