[PATCH v3 1/3] hw/timer/i8254_common: Share "iobase" property via base c


From: Bernhard Beschow
Subject: [PATCH v3 1/3] hw/timer/i8254_common: Share "iobase" property via base class
Date: Tue, 23 May 2023 21:56:06 +0200

Both TYPE_KVM_I8254 and TYPE_I8254 have their own but same implementation of
the "iobase" property. The storage for the property already resides in
PITCommonState, so also move the property definition there.
