soc/amd/*/acpi/mmio.asl,sb_fch.asl: change AAHB's _STA back to method

Commit 396fb3db74 ("soc/amd/*/acpi/mmio.asl,sb_fch.asl: hide AAHB
device") didn't only change the visibility of the device, but also
changed the _STA method to a name. While this worked, the specification
says that _STA is supposed to be a method, so change it back to being a
method.
