aspeed: Fix realize error API violation

Browse source 
The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL.  Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call.

aspeed_soc_ast2600_realize() and aspeed_soc_realize() are wrong that
way: they pass &err to object_property_set_int() and
object_property_set_bool() without checking it, and then to
sysbus_realize().  Harmless, because the former can't actually fail
here.

Fix by passing &error_abort instead.
