hw/rtc/mc146818rtc: Convert to 3-phase reset (Resettable interface)

TYPE_MC146818_RTC is an ISA device, so its DeviceClass::reset()
handler is called automatically when its qbus parent is reset
(we don't need to register it manually).

We have 2 reset() methods: a generic one and the qdev one.
Merge them into a reset_enter handler (keeping the IRQ lowering
to a reset_hold one), and remove the qemu_register_reset() call.
