AEST V2 was published[1], add V2 support based on AEST V1.
Fix some code styling issues as well.
Change from v1:
- fix error variable name in struct acpi_aest_node_interface_64k.

Patch1 is just a fix to follow kernel code style. Patch2 had merged to
acpica project, PR link can be see in patch2 comment:

IIUC such changes are not allowed as ACPICA changes are always imported
from the external project. So you have to take same route as patch2

Thanks, this will then get imported into kernel next time ACPICA changes
get merged which usually happens regularly.

In ACPICA, all struct use typedef which is not allowed in kernel:
It's a **mistake** to use typedef for structures and pointers[1].
I see all other structs in actbl2.h follow this rule, so I fix all
typedef in AEST struct to follow kernel code style. But i can not apple
this fix in ACPICA. Patch1 is just a kernel patch.

No patches from the kernel tree applies to APCICA because of some variations
in the coding style that the import script modifies when applying to the
kernel. So make similar changes in APCICA project and send it there. It will
get imported if it gets merged there.
