The registers.py generator outputs expressions with subtractions
into the C code of debug_defines.{h,c} in this form:
```
((XLEN) + -6ULL)
```
Such code may look awkward to code readers and also triggers GCC's
-Wconversion warnings (when enabled).
Fix the generator to produce the expressions with subtraction
in a natural form:
```
((XLEN) - 6ULL)
```
