amdk8/amdfam10: Use CAR_GLOBAL for sysinfo
This gets rid of the somewhat unstructured placement of AMD's
sysinfo structure in CAR.
We used to carve out some CAR space using a Kconfig variable,
and then put sysinfo there manually (by "virtue" of pointer magic).
Now it's a variable with the CAR_GLOBAL qualifier, and build
system magic.
For this, the following steps were done (but must happen together
since the intermediates won't build):
- Add new CAR_GLOBAL sysinfo_car
- point all sysinfo pointers to sysinfo_car instead of GLOBAL_VAR
- remove DCACHE_RAM_GLOBAL_VAR_SIZE
- from CAR setup (no need to reserve the space)
- commented out code (that was commented out for years)
- only copy sizeof(sysinfo) into RAM after ram init, where
before it copied the whole GLOBAL_VAR area.
- from Kconfig
