Note that I have compile-tested this, which should've caught any attempt
to modify a const TypeInfo. And I have reviewed the patch to not do any
accidental refactoring.

While this is close to a touch-all patch, those lines are rarely
touched, so mainly QOM'ification patches touching .name would be
affected, i.e. at this time Fred's and mine.
Previous art are patches by Stefan W. to make MemoryRegionOps const.

After this patch, two occurrences of non-const static TypeInfo remain,
inside qom/object.c for Object and Interface respectively.
Plus non-static, non-const TypeInfos in eepro100, EHCI, UHCI and CPUs.
