amd/acpi: Clean up SMBus references.

Replace the AMD SMBus section with the equivalent SB800 smbus.asl
include or remove already commented-out sections.

Verified by running the cpp preprocessor over the DSDTs and diffing the
results against this patch.

The only change is in src/mainboard/siemens/sitemp_g1p1/dsdt.asl, where
someone added RADD and SADD to the OpRegion, but those are unused, so
removing them is fine.
