Right now, if anything internal changes with a uvm object, diverse
places in the tree need to be touched to update the object
initialisation with respect to that.
So, make a function (uvm_initobj) that takes the refcount, object and
pager ops and does this initialisation for us. This should save on
maintainance in the future.
looked good to fgs@. Tedu complained about the British spelling but OKed
it anyway.
