checkpatch: add target_ulong to typelist

In some occasions, a patch [1] can start with a hunk containing a
simple type cast. At the time annotate_values() is run, the type is
unknown and the cast type is misinterpreted as a identifier, resulting
in an error if it is followed with a negative value:

	ERROR: spaces required around that '-' (ctx:WxV)

It seems complex to catch all possible types in a cast expression. So,
as a fallback solution, let's add some common qemu types to the
typeList array.
