Add the DBG2 table generated with
tests/data/acpi/rebuild-expected-aml.sh

Signed-off-by: Eric Auger <eric.auger@redhat.com>

Tested by comparing the content with the table generated
by EDK2 along with the SBSA-REF machine (code generated by
DynamicTablesPkg/Library/Acpi/Arm/AcpiDbg2LibArm/Dbg2Generator.c).

I reused the Generic Address Structure filled by QEMU in the SPCR, ie.
bit_width = 8 and byte access. While EDK2 sets bit_width = 32 and
dword access. Also the name exposed by acpica tools is different:
'COM0' in my case where '\_SB.COM0' in SBSA-REF case?

Here is the human readable content:
