soc/amd: add ACPI code for I3C controller
Add the I3C controllers to the ACPI tables. Most of the ACPI code needed for that is added to the DSDT, since everything, but the enable status of the I3C MMIO devices is known at build-time. To handle the I3C controller enable status, each ACPI device contains the STAT name with the value of 0 in the DSDT and when the device is enabled this STAT name will be overridden in the SSDT. TEST=OS loads the I3C kernel modules on amd/birman_plus.
