ACPICA: Add support for ASPT table in disassembler

Browse Source 
ACPICA commit 6771f8b758299bd383bab145d5fd36ec229b2d70

ASPT is the AMD Secure Processor table, found in Hyper-V VMs when SNP
isolation is exposed to the VM and in some high-end AMD servers. This
commit adds support for rev 1 of the ASPT spec in the disassembler.
