PS9: 
If possible, please contain the changes within `soc_util.h`.

Also, is this really FSP 2.4 specific? Or is it just the next soc-specific
header revision and the current architecture happens to be FSP 2.4 atm?
I would not expect any of this in the FSP 2.4 spec.

File src/soc/intel/xeon_sp/include/soc/fsp_adoption.h:

PS9, Line 21: #define xSTACK_RES UDS_STACK_RES
If the types are compatible, wouldn't it be enough to
```
#define STACK_RES UDS_STACK_RES
```
for the new headers? Then we wouldn't have to change all occurrences in
the C code.
