pseries: Make the PAPR RTC a qdev device
At present the PAPR RTC isn't a "device" as such - it's accessed only via
firmware/hypervisor calls, and is handled in the sPAPR core code. This
becomes inconvenient as we extend it in various ways.
This patch makes the PAPR RTC a separate device in the qemu device model.
For now, the only piece of device state - the rtc_offset - is still kept in
the global sPAPREnvironment structure. That's clearly wrong, but leaving
it to be fixed in a following patch makes for a clearer separation between
the internal re-organization of the device, and the behavioural changes
(because the migration stream format needs to change slightly when the
offset is moved into the device's own state).
