southbridge/amd/sb600: Update HPET base address with #define
The SB600 code had the base address of the HPET hardcoded throughout.
It looks like the plan was to have it be updated in ACPI if needed,
but this wasn't ever implemented. The variable names being used to
do this update were the same, causing an IASL warning. Because of
this, the operation to update the HPET address actually did nothing.
This was fine, because it didn't actually need to be updated.
- Replace all that code with a #define.
- Add and update some comments in the same area.
Fixes IASL warning:
dsdt.aml 1505: Store(HPBA, HPBA)
Warning 3023 - ^ Duplicate value in list (Source is the
same as Target)
