[0/4] Improve default object property_add uint helpers

Message

This improves the family of object_property_add_uintXX_ptr helpers by enabling
a default setter when desired. To prevent an API behavioural change (from
clients that already used these helpers and did not want a setter), we add a
"readonly" parameter that allow clients to only have a getter. Patch 1 enhances
the API and modify current users.

While modifying the clients of the API, a couple of improvement opportunities
were observed in ich9. These were added in separate patches (2 and 3).

Patch 3 cleans up a lot of existing code by moving various objects to the
enhanced API. Previously, those objects had their own getters/setters that only
updated the values without further checks. Some of them actually lacked a check
for setting overflows, which could have resulted in undesired values being set.
The new default setters include a check for that, not updating the values in
case of errors (and propagating them).

Felipe Franciosi (4):
  qom/object: enable setter for uint types
  ich9: fix getter type for sci_int property
  ich9: Simplify ich9_lpc_initfn
  qom/object: Use common get/set uint helpers
