These look like reports about bugs in ASL.
Have you tried booting some recent Linux on this system?  Not sure if ACPI error
logging would be enabled there by default.  But it would be interesting if Linux
reports the same problems.

My opinion is that the mistake is most likely in the ASL, but it's possible that
there is something incorrect or untypical about how FreeBSD calls the ASL.
