Since 39bffca203 (qdev: register all
types natively through QEMU Object Model), TypeInfo as used in
the common, non-iterative pattern is no longer amended with information
and should therefore be const.
Fix the documented QOM examples:
sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h
Since frequently the wrong examples are being copied by contributors of
new devices, fix all types in the tree:
sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c
sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c
This also avoids to piggy-back these changes onto real functional
changes or other refactorings.
