hw/display/tcx: Remove superfluous OBJECT() typecasts

The tcx_initfn() function is already supplied with an
Object *obj pointer, so there is no need to cast the
state pointer back to an Object pointer all over the
place. And while we're at it, also remove the superfluous
"return;" statement in this function.
