Clean-ups: qom-ify serial and remove QDEV_PROP_PTR

Hi,

QDEV_PROP_PTR is marked in multiple places as "FIXME/TODO/remove
me". In most cases, it can be easily replaced with QDEV_PROP_LINK when
the pointer points to an Object.

There are a few places where such substitution isn't possible. For
those places, it seems reasonable to use a specific setter method
instead, and keep the user_creatable = false. In other places,
proper usage of qdev or other facilies is the solution.

The serial code wasn't converted to qdev, which makes it a bit more
archaic to deal with. Let's convert it first, so we can more easily
embed it from other devices, and re-export some properties and drop
QDEV_PROP_PTR usage.
