[Qemu-devel] [PULL 10/28] target-i386: Replace custom apic-id setter/getter with static property

[Eduardo Habkost <ehabkost@redhat.com>]

From: Igor Mammedov <imammedo@redhat.com>

Custom apic-id setter/getter doesn't do any property specific
checks anymore, so clean it up and use more compact static
property DEFINE_PROP_UINT32 instead.
