Make all static TypeInfos const

Since 39bffca2030950ef6efe57c2fac8327a45ae1015 (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.
